摘要： Techniques are provided to support successive interference cancellation (SIC) receiver processing with selection diversity whereby each of N T transmit antennas may be turned on or off. One symbol stream may be transmitted from each transmit antenna. A SIC receiver recovers the transmitted symbol streams in a specific order. Up to N T ! orderings are evaluated. For each ordering, N T post-detection SNRs are obtained for N T transmit antennas and used to determine N T data rates, where the data rate is zero if the post-detection SNR is worse than a minimum required SNR. An overall data rate is computed for each ordering based on the N T data rates. The ordering with the highest overall data rate is selected for use. Up to N T symbol streams are processed at the data rates for the selected ordering and transmitted. The transmitted symbol streams are recovered in accordance with the selected ordering.

摘要： Techniques for efficient determination of a macroblock's spatial predictability quality with respect to the H.264 specification are provided. A device comprises a processor operable to estimate a first subset of spatial prediction modes based on a first pixel subset of a current subblock of an intra-frame. The processor is also operable to estimate a second subset of spatial prediction modes based on a second pixel subset of the current subblock. The first subset of prediction modes is different from the second subset of prediction modes.

摘要： To broadcast different types of transmission having different tiers of coverage in a wireless broadcast network, each base station processes data for a wide-area transmission in accordance with a first mode (or coding and modulation scheme) to generate data symbols for the wide-area transmission and processes data for a local transmission in accordance with a second mode to generate data symbols for the local transmission. The first and second modes are selected based on the desired coverage for wide-area and local transmissions, respectively. The base station also generates pilots and overhead information for local and wide-area transmissions. The data, pilots, and overhead information for local and wide-area transmissions are multiplexed onto their transmission spans, which may be different sets of frequency subbands, different time segments, or different groups of subbands in different time segments. More than two different types of transmission may also be multiplexed and broadcast.

摘要： According to the invention, quantization encoding is conducted using the probability density function of the source, enabling fixed, variable and adaptive rate encoding. To achieve adaptive encoding, an update is conducted with a new observation of the data source, preferably with each new observation of the data source, preferably with each new observation of the data source. The current probability density function of the source is then estimated to produce codepoints to vector quantize the observation of the data source.
