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.
Claims20
A method, comprising:
- concatenating multiple groups of bits into a single block;
- encoding the single block;
- generating symbols from the encoded single block;
- distributing the symbols across multiple spatial streams, wherein each spatial stream is associated with one or more respective antennas;
- and
- performing a cyclic shift of each spatial stream such that adjacent bits are mapped to different tones on different antennas of the one or more respective antennas.

A system, comprising:
- multiple antennas;
- a transceiver array to couple to said multiple antennas;
- a diversity agent coupled to said transceiver array, the diversity agent to concatenate multiple groups of bits into a single block having a block size,
- encode the single block,
- generate symbols from the encoded single block,
- distribute the symbols across multiple spatial streams, wherein each spatial stream is associated with a respective antenna of the multiple antennas, and
- perform a cyclic shift of each spatial stream such that adjacent bits are mapped to different tones on different antennas of the multiple antennas.

An article comprising a computer-readable storage medium containing instructions that if executed enable a system to:
- concatenate multiple groups of bits into a single block having a block size;
- encode the single block;
- generate symbols from the encoded single block;
- distribute the symbols across multiple spatial streams, wherein each spatial stream is associated with one or more respective antennas;
- and
- perform a cyclic shift of each spatial stream such that adjacent bits are mapped to different tones on different antennas of the one or more respective antennas.
