Abstract:
1. A receiver system for receiving and decoding modulated signals transmitted from a plurality of transmitter antennae and received at a plurality of receiver antennae, comprising: demodulation circuitry, coupled to the receiver antennae, for demodulating the received signals into a plurality of frequency domain datastreams; and shared decoder logic circuitry, for first decoding the plurality of frequency domain datastreams to generate estimated signals transmitted from each of the transmitter antennae according to maximum-likelihood (ML) estimation, and for then Viterbi decoding at least a portion of the estimated transmitted signals according to an error correction code; wherein at least some circuits of the shared decoder logic circuitry are used both in the decoding of the plurality of frequency domain datastreams to generate the estimated transmitted signals and in the decoding of those estimated transmitted signals according to the error correction code.
