Abstract: Apparatus and method to provide unified STTD/CLTD dedicated pilot processing in a wireless receiver. The technique allows different set of parameters to be introduced to a same processing module to process STTD and CLTD diversity signals to recover a pilot signal. Introducing another set of parameters to the processing module also allows processing of a non-diversity signal to recover a pilot. The unified processing of STTD/CLTD signals is achieved by converting STTD/CLTD pilot bits as Hadamard-like bits and processing these bits along with orthogonal pilot bits which are encoded as Hadamard encoded bits.

Abstract: A system and method for enhanced accuracy in cable diagnostics of cable length. Conventional cable diagnostics such as time domain reflectometry can be used to determine cable length. This conventional technique can have accuracy limitations in certain situation such as with perfectly terminated cable. A cable length can also be determined through the use of link delay measurements that are based on clock synchronization between nodes in a network. Notwithstanding the accuracy issues of these link delay measurements, overall accuracy can be increased through the combination of the two cable length delay measurements into a final estimate.

Abstract: Embodiments of the present invention relate generally to reconstruction filtering. In particular, embodiments enable highly linear, highly programmable, and easily reconfigurable reconstruction filters. Further, embodiments provide substantial power consumption, area, and cost savings compared to conventional solutions. For example, embodiments use all-passive filtering and substantially reduce active elements compared to conventional solutions. As a result, significant reductions in required area, noise, and power consumption can be achieved. In addition, embodiments perform filtering solely in the current domain, thereby eliminating the non-linear voltage-to-current conversion used in conventional circuits and enabling highly linear filtering. Furthermore, embodiments are highly programmable and easily reconfigurable without the use of tunable capacitors. As such, embodiments are very suitable solutions for multi-band multi-mode wireless transmitters.

Abstract: Command packets for a personal video recorder that provides for a transport stream (TS) that contains data and also includes a transport packet (TP)/TS formatted command packets. The TP/TS formatted command packet may be communicated between any number of devices, including multiple chips, multiple boards, and multiple processors. A decoder is able to decode the TP/TS formatted command packet and to perform the appropriate operation on data portions of the TS. When a TS is provided to a device not having the capability to perform the proper decoding of the TP/TS formatted command packet, that particular packet may be deemed as being unidentified (or unknown) adaptation field data. Alternatively, the packet may be identified as being corrupted data and/or irrelevant data.

Abstract: Methods and systems for mitigating a voltage standing wave ratio in a transmitter are disclosed and may comprise calibrating an output power of a power amplifier integrated within a chip using a resistor that models an impedance of an antenna that is externally coupled to the amplifier while the antenna is decoupled. The gain and output power of the amplifier may be determined utilizing the known resistance and a voltage that is measured at an input of the power amplifier, or at a number of points prior to the power amplifier. When the antenna may be coupled to the transmitter, the transmitter output power may then be controlled utilizing the voltage measurements prior to the power amplifier to avoid measuring reflected waves in instances when the antenna impedance may vary. The power amplifier may be of a design that comprises reverse isolation to reduce reflected waves from the antenna.

Abstract: An interrupt sensitive extract byte instruction scheme is presented herein. The interrupt sensitive extract by instruction extracts bytes from data, depending on the presence of an interrupt. The extract byte instruction extracts bytes from data in the absence of the interrupt and does not extract bytes in the presence of the interrupt. The interrupt can be triggered by a set of counters that count the number of extracted bytes. By loading the counters with a particular number, the interrupt can be generated when the particular number of data bytes is extracted.
