Method and apparatus for transmitting communication signals using transmission space diversity and frequency diversity |
摘要 |
A transmitter diversity assembly and an associated method for a radio transmitter. When coupled to a radio transmitter to form a portion thereof, signal diversity is created to overcome multi-path fading. A plurality of antennas are freely selectable to be coupled to receive bursts of a communication signal, modulated to be transmitted on any of selected carriers. By altering the carriers upon which the bursts of the communication signal are transmitted and the spatially-separated antennas used to transduce the bursts of the communication signal, both transmission space diversity and frequency diversity is created.
