摘要： The invention relates to a method of iterative multi-layer decoding of a multimedia communication signal, wherein persistent bits from various upper layers of the employed protocol stack are used in error correction decoding at a lower error-correction layer. The method includes saving persistent bits from successfully decoded FEC frames in memory, and using a subset of the saved bits in decoding of future frames. A smart controller is used to analyze frames for the presence and location of persistent bits, for saving thereof in memory, and for inserting saved persistent bits into a next frame at successive decoding iterations thereof.

摘要： A system has a first transmitter for transmitting a first wireless signal within a first frequency. A second transmitter is for transmitting a second wireless signal with overlapping frequency. The first transmitter and the second transmitter are disposed sufficiently proximate to another such that the wireless signals substantially interfere resulting in a combined wireless signal with negative SNR for each of the first wireless signal and the second wireless signal, the negative SNR being a result of at least the other of the first wireless signal and the second wireless signal. A receiver is located for receiving a received wireless signal comprising substantially interfering encoded data signals having negative SNR. The receiver is for selecting from the substantially interfering encoded data signals a signal of interest and for decoding said signal of interest relative to at least the other substantially interfering data signal within the received wireless signal.
