Signal processing apparatus and method

摘要

A signal processing apparatus (200) comprises a plurality of receive antennas (214a-d) arranged to receive a composite signal containing a plurality of transmitted symbols. A joint detector-decoder (218) iteratively enumerates most probable symbols received at the receive antennas (214a-d) using an enumeration constraint. A processor (220) determines a bit stream corresponding to each most probable received symbol. A method of signal processing for MIMO systems is also disclosed.
