Communication system modulating/demodulating data using antenna patterns and associated methods

摘要

A wireless communication system includes a transmitter comprising a serial-to-parallel converter for converting serial data bits to a parallel bit stream, a signal mapper coupled to the serial-to-parallel converter and an antenna selector coupled to the serial-to-parallel converter. The signal mapper receives as input a first group of bits from the parallel bit stream, and maps the first group of bits to a channel symbol. The antenna selector receives as input a second group of bits from the parallel bit stream. A transmit antenna array is coupled to the antenna selector and to the signal mapper. The transmit antenna array generates a plurality of transmit antenna patterns with one of the transmit antenna patterns being selected for transmitting the channel symbol based upon the second group of bits from the antenna selector.
