Abstract

In one embodiment, a multi-input/multi-output system (100) includes a receiver (104), processor, coded bit scrambler (114), coded bit descrambler (130), and transmitter (102). The receiver (104) generates demodulated symbol streams corresponding to a received signal. The processor generates coded bit sequences from source bit streams when operating in a transmit mode and bit log-likelihood ratio sequences from the information bit streams when operating in a receive mode. The coded bit scrambler (114) scrambles the coded bit sequences to generate scrambled bit streams when in the transmit mode. The coded bit descrambler (130) descrambles the log-likelihood ratio sequences by a real-valued descrambling sequence when operating in the receive mode, and also removes the effect of a scrambling sequence. The transmitter (102) generates a transmit signal corresponding to the scrambled bit streams.
