Adaptive beam-time coding method and apparatus

摘要: A radio system includes a base station and remote station. The space-time encoder, an antenna system, transmitter, receiver, power management controller. encoder encodes stream of symbols into first second coded signals, the transmitter transmits signals at respective initial transmit powers from so as to form radiation patterns. receiver receives coefficient indicator information station, controller determines adjusted based on information. In alternative embodiment, circuit determine angular spectrum, transmitter. in beams that are contained within spread spectrum.
