A method and system performs blind joint channel estimation and signal detection in a communication system that includes multiple channels for transmitting symbols. The multiple channels are estimated using a small number of symbols initially received through the multiple channels. When the channels have been estimated, a single best channel is selected. From then on, the bulk of the symbols are detected only on the best channel, while the best channel is updated.

Trellis based maximum likelihood signal estimation method and apparatus for blind joint channel estimation and signal detection

A method for communicating a bit stream using turbo coding encodes each input bit in the bitstream using a single 1/3 rate turbo encoder to produce a set of three bits. One of the three bits in each set is repeated to produce a set of four bits for each input bit. A time interval between the four bits is increased before transmitting the set of four bits on a communications channel. In a receiver, the time interval between the set of four bits received via the communications channel is decreased using a de-interleaver. The received set of four bits are diversity combine into a received set of three bits, and then a single 1/3 rate turbo decoder is used to recover an output bit for each input bit.
