ABSTRACT:
A system, apparatus, method and article to manage diversity for a wireless multicarrier communication system are described. An apparatus may include a diversity agent to couple to a transmitter, the diversity agent to convert a determined number of input bits into symbols, interleave the symbols across multiple spatial streams, and map the symbols to tones for each spatial stream. Other embodiments are described and claimed.
