摘要： A process capable of employing compression and decompression mechanism to receive and decode soft information is disclosed. The process, in one aspect, is able to receive a data stream formatted with soft information from a communication network such as a wireless network. After identifying a set of bits representing a first logic value from a portion of the data stream in accordance with a predefined soft encoding scheme, the set of bits is compressed into a compressed set of bits. The compressed set of bits which represents the first logic value is subsequently stored in a local memory.

摘要： A method and apparatus for turbo code decoding are provided to reduce memory consumption during calculation of state metrics. In an embodiment of a turbo code decoder, a natural recursion unit comprises a plurality of add-compare-select (ACS) units performing natural recursion operations to generate a state metric. The original state metric is then converted to a differential metric before being stored into a memory device. The differential metric contains less data than the state metric so that memory consumption is reduced. To restore the original state metric from the differential metric, a plurality of revival units operating in parallel is provided. Thereby, the state metric is reacquired from the differential metric, and a Log Likelihood Recursion (LLR) operation is accordingly performed by an LLR unit.

摘要： Spatial-temporal compression of sensing data from a plurality of sensors involves using a plurality of sensors to obtain measured physical data associated with a plurality of sensed elements. At each of a plurality of sampling times a set of N sampled data is acquired from the N sensed elements corresponding to the measured physical data. The sets of sampled data are analyzed to obtain statistical characteristic information. Thereafter, one or more frames of compressed data is generated using the statistical characteristic information to facilitate temporal and spatial data compression.
