Abstract: A method for improving the performance of OFDM (Orthogonal Frequency Division Multiplexing) systems addresses the channel estimation, equalization and decoding problems of conventional techniques and provides improved performance in a wide range of operating conditions that include varying Signal to Noise Ratio (SNR) levels, data rates, and fading channels. The method teaches SNR based selection in the use/choice of a smoothing filter. The invention further teaches using a smoothing filter in combination with Decision Feedback Equalization (DFE), using a smoothing filter in combination with WCSI (Weighted Channel State Information) decoding, which may be combined with DFE, and data rate based selection (for example, in IEEE 802.11a/g applications) in employing a decision feedback based correction.

Abstract: A technique to enhance audio quality of a quantized audio signal when a perceptual audio coder is operating at low bit rates. The perceptual audio coder uses a modified two-loop quantization technique that maintains audio quality at medium to high bit rates while eliminating artifacts at low bit rates. The perceptual audio coder saves vanishing bands by stealing bits from surviving bands to reduce artifacts at low bit rates.

Abstract: A method for designing a multi-threaded processing operation that includes, e.g., multimedia encoding/decoding, uses an architecture having multiple processors and optional hardware accelerators. The method includes the steps of: identifying a desired chronological sequence of processing stages for processing input data including identifying interdependencies of said processing stages; allotting each said processing sage to a processor; staggering the processing to accommodate the interdependencies; selecting a processing operation based on said allotting to arrive at a subset of possible pipelines that offer low average processing time; and, choosing one design pipeline from said subset to result in overall timing reduction to complete said processing operation. The invention provides a multi-threaded processing pipeline that is applicable in a System-on-Chip (SoC) using a DSP and shared resources such as DMA controller and on-chip memory, for increasing the throughput.

Abstract: A method and algorithm for IP address lookup for packet forwarding, finds a longest prefix match for a destination address of n bits, using 2n/2 entries in a lookup table, expanding a given IP address to be matched if its prefix length is more than n/2, and, completing a lookup operation using the table. The number ‘n” may be 32 or otherwise. An example teaches an IP address lookup table with a maximum address size of 32 bits, using a lookup table with 216 entries. Further, if an IP prefix length is more than 16 bits, then the given address to be matched is expanded to its full prefix length before the lookup operation. The algorithm takes only two memory references for specific hardware, such as IXP1200. For generic hardware, it takes only three memory references. Also taught is a computer readable medium having the method encoded therein.

Abstract: A system and method to analyze interactions among software artifacts within enterprise applications. The system includes an artifact analyzer module an artifact code parsing module and an artifact token processing module. The artifact analyzer module generates artifact tokens associated with trigger points in which processing control passes between a first software object and a second software object in the enterprise application and an interaction token repository for storing artifact tokens. The artifact tokens describe identity of the first software object, ownership of the first software object containing the trigger point, a location within first software object of the trigger point, and identity of the second software object. These artifact tokens are stored within an interaction token repository for later use.

The script-transaction is carried out in response to a script input. The method includes truncating at least one table, which is being modified by at least one of a persistent trigger and a non-persistent trigger. The persistent trigger updates a table and the non-persistent trigger performs one of an insert operation and a delete operation on a table. Further, the method includes executing a non-persistent trigger corresponding to each truncated table of the database in a predefined-update-sequence. Also, the method includes executing at least one persistent trigger corresponding to each truncated table of the database.

Abstract: The proposed technique provides simultaneous read and writes from a display controller using low-cost SDRAMs. This is achieved, in one example embodiment, by receiving a sequence of video frames at a first variable frame rate. A first video frame is then written in a first single-ported memory. The first video frame is then read from the first single-ported memory upon completing the writing of the first video frame in the first single-ported memory. The reading of the first video frame is then repeated from the first single-ported memory to maintain a second frame rate. The second frame rate is higher than the first variable frame rate. A second video frame is then written in a second single-ported memory upon completing the writing of the first video frame in the first single-ported memory such that the writing of the first video frame and the second video frame is at the first variable frame rate.

Abstract: A method and apparatus for a frequency shift keying (FSK) demodulator use a configuration to improve the autocorrelation for better receiver performance. The demodulator uses parallel first and second lines connected to the same input signal, the first line having a delay element to provide an integer-delay of M, the second parallel line having a filter for causing a group delay of ?+M where ? is fractional, and a multiplier for receiving the signals from said first and second lines and generating a resultant signal from which a base band signal can be recovered. The resultant signal is passed through a low pass base band filter to recover the base band signal. ? may have a value of 3.25 and M may be 6. The demodulator may selectively be implemented in caller ID service and in low end modems chosen from a group comprising V.21, Bell 103, V.23 and Bell 202A modems.

Abstract: A decision feedback equalizer (DFE) has an inter symbol interference (ISI) loop and inter chip interference (ICI) loop. A buffer at the input of the DFE loop receives a (CCK based data rate) signal coming into the DFE, retains a predetermined number of chips from each incoming symbol and assists to meet timing requirements by chip management. An outgoing rate for the chips from the buffer may depend on the incoming rate and may be higher than the incoming rate by a known factor. A method of designing a configuration for the DFE takes into consideration the timing delay in the loops. The operation within the DFE loop is pipelined, and any latency due to the pipelining is handled at a CCK demodulator. A method for designing the DFE architecture and an article comprising a storage medium with instructions thereon for executing the method, are also disclosed.

Abstract: A method for designing a decision feedback equalizer (DFE) that handles packet based input data signals uses an inter symbol interference (ISI) removal loop and an inter chip interference (ICI) removal loop which is nested inside the ISI loop, for maximum interference removal and limited error propagation. The DFE may use a feed forward filter and a series connected chip-flow control buffer for receiving the input data signals. The DFE of the invention has application in 802.11 b PHY and 802.11 g PHY scenarios and any application involving a DFE with the need for minimum error propagation. Taught herein is a combined weighted DFE with erasure provision and interference removal in an optional two step mechanism. An article comprising a computer storage medium to execute the DFE design method is also disclosed.
