ABSTRACT:
A multiple stream cyclic-shifted delay transmitter including a baseband processing module and a plurality of RF transmit sections. The baseband processing module is operably coupled to convert outbound data into a plurality of transmit baseband signal streams and cyclic-shift delay at least one of the plurality of transmit baseband signal streams to produce at least one cyclic shift delayed transmit baseband signal stream. The plurality of RF) transmit sections is operably coupled to convert the plurality of transmit baseband signal streams and the at least one cyclic-shift delayed transmit baseband signal stream into a plurality of RF signals.
