Patent number: 7110445Abstract: The present invention provides an apparatus, system and method of peak-to-average reduction of an oversampled signal for a digital communication system. Peak detection 504 and width measurement 504 are advantageously combined in which a peak portion or multiple peak portions of an input signal that exceeds a predetermined threshold is detected and a width of the peak portion is determined. The peak detection and width measurement are further combined with a novel variable width shape generation methodology 506 in which a variable width shaping response is applied 510 to the peak portion responsive to the peak portion width. Additionally, a novel receiver technique 1390 can be included to reduce or eliminate the upstream BER impact using downstream oversampled shaping.Type: GrantFiled: August 28, 2001Date of Patent: September 19, 2006Assignee: Texas Instruments IncorporatedInventor: Peter J.

Patent number: 7031457Abstract: A digital input signal is analyzed by a peak detector (210) configurable to trigger a first logic signal (260) if the peak detector detects the digital input signal level crossing a certain threshold. The threshold value can be modified by an overhead. The amplifier (250) employs a plurality of supply rails of differing voltages (253, 255) as a function of the logic signals. A digital signal delay element (220) may delay the signal to allow sufficient time for the amplifier to switch between supply sources. A logic delay element (280) may delay transmittal of the first logic signal by the peak detector to compensate for signal delay caused by a filter. A hold element (270) ensures that the first logic signal is applied to the output amplifier for a given amount of time.Type: GrantFiled: November 30, 2001Date of Patent: April 18, 2006Assignee: Texas Instruments IncorporatedInventor: Peter J.

Patent number: 7027589Abstract: A central office modem (50) that includes the capability of single-ended loop testing (SELT) is disclosed. The modem (50) includes a digital signal processor (54), a codec (56), line driver and receiver circuitry (58), and a hybrid circuit (60), by way of which a subscriber loop (LOOP) can be driven and sensed. The line driver and receiver circuitry (58) may include a transformer (74a, 74b) for driving the loop (LOOP), or the output may be capacitively coupled. The line driver and receiver circuitry (58) includes active termination, by way of operational amplifiers (80a, 80b). Switches (82a, 82b; 84a, 84b) are provided to selectively enable and disable the active termination function, and to selectively bypass or include the hybrid circuit (60). This control of the line driver and receiver circuitry (58) provides the ability to calibrate out its own characteristics, providing high precision SELT measurements of the load impedance type, and of frequency domain reflectometry, and time domain reflectometry.Type: GrantFiled: November 27, 2002Date of Patent: April 11, 2006Assignee: Texas Instruments IncorporatedInventors: Hao Shi, Peter J.

Patent number: 5263121Abstract: A neural network solution for routing calls through a three stage interconnection network selects an open path through the interconnection network if one exists. The neural network solution uses a neural network with a binary threshold. The weights of the neural network are fixed for all time and therefore are independent of the current state of the interconnection network. Preferential call placement strategies are implemented by selecting appropriate external inputs to the neural network. An interconnection network controller stores information reflecting the current usage of the interconnection network and interfaces between the interconnection network and the neural network.Type: GrantFiled: September 12, 1991Date of Patent: November 16, 1993Assignee: Tellabs, Inc.Inventors: Peter J.
