Abstract: A configurable transmitter for a wireless communication system may include a flexible block coder, an IFFT block, an analog and RF block, and an antenna coupled in series. The flexible block coder may advantageously perform forward error correction and mapping of a data stream to generate a processed data vector. To perform these functions, the flexible block coder may include a data formatter and a multiplier. The data formatter may format the data stream into an output vector, whereas the multiplier may multiply the output vector by a configurable channel coding matrix to generate the processed data vector. The size of the output vector may be a reflection legacy compatibility and data rate. The size of the processed data vector is equal to a product of the output vector and an inverse of a coding rate. The channel coding matrix may be compressed.

Abstract: Various techniques for dynamically reducing power usage in a wireless receiver are disclosed. A receiver unit receives a wireless signal over a channel and processes the wireless signal, including dynamically changing one or more of the settings of the receiver unit to control its power usage. These setting are changed in response to one or more power setting values that are generated based on a first set of information that includes state information for the channel. The receiver unit may dynamically change a first setting that causes the bias current applied to an analog-to-digital converter to be changed. The channel state information may include information indicative of a received signal strength indication (RSSI), information indicative of a packet error rate (PER) for packets encoded on the wireless signal, and header error check (HEC) and/or cyclical redundancy check (CRC) errors for data packets encoded on the wireless signal.

The received passphrase is then used for authenticating the device for one or more network interfaces. The authentication can be performed irrespective of a communication medium used by the network interfaces.

Abstract: A high sensitivity GPS receiver includes an acquisition engine and a tracking engine. The acquisition engine processes GPS satellite data at data rate that is substantially equal to twice the coarse acquisition (CA) code chip rate. This data rate advantageously enables the acquisition engine to process GPS satellite data with relatively less hardware area than traditional GPS acquisition approaches. In one embodiment, the high efficiency acquisition engine may be over-clocked, thereby allowing different phases of a CA code to be correlated quickly. The tracking engine can advantageously processes GPS satellite data at a data rate that does not have an integer relationship to the CA code chip rate.

Abstract: A mechanism for processing beamforming steering matrices in a transceiver system. A plurality of beamforming steering matrices associated with a plurality of subcarriers of an RF signal received at the transceiver system are generated. The beamforming steering matrices are compressed and stored. The beamforming steering matrices may also be grouped or sub-sampled prior to being stored.

Prior to ungrouping the beamforming steering matrices, a phase difference between corresponding beamforming steering vectors of consecutive beamforming steering matrices is determined. Phase rotation is performed on the corresponding beamforming steering vectors based on the determined phase difference associated with the corresponding beamforming steering vectors to improve phase continuity between consecutive beamforming steering matrices.

Abstract: A polar transmitter includes a phase monitoring unit for monitoring input modulating data. When a phase transition exceeds a phase transition threshold, the phase monitor unit can signal an amplitude negation unit to invert the amplitude data coupled to the polar amplifier. The phase monitoring unit can also add an offset to the phase data that is provided to a frequency synthesizer. In another embodiment, when the phase transition threshold is exceeded, the phase monitoring unit can trigger inverting differential frequency data coupled to the polar amplifier. In one embodiment, the phase offset and the amplitude negation are applied until a second phase transition value exceeding the phase transition threshold is detected. If such an event is detected, then the input amplitude data is no longer inverted and the phase offset value is no longer added to the modulating data.
