Iterative multi-stage detection technique for a diversity receiver having multiple antenna elements

A system for receiving a signal with an antenna array, comprising:

• at least one processor that receives K replicas of the signal utilizing one or more of corresponding K antenna elements of the antenna array, wherein the K replicas include N replicas and M other replicas of the received signal;
• said at least one processor multiplexes the N replicas and the M replicas of the signal into a multiplexed signal provided to a single processing chain;
• said at least one processor removes interference due to the N signals from the multiplexed signal;
• said at least one processor demultiplexes, after the interference due to the N signals is removed, the M signals from the multiplexed signal, and thereby generates M detected signals;
• said at least one processor removes interference due to the M signals from the multiplexed signal;
• and
• said at least one processor demultiplexes, after the interference due to the M signals is removed, the N signals from the multiplexed signal, and thereby generates N detected signals.
