User focus technology for wireless communication systems

摘要

A transmitter , a receiver , a wireless communication system and method in a system comprising a plurality of propagation paths capable of transmitting a signal to be transmitted from the transmitter and the transmitter is formed between the receiver to the receiver . The method includes a first signal , from the transmitter to the receiver , is transmitted through a single transmission path of the plurality of propagation paths , and receives a first signal at the receiver , the first signal run the channel estimation , and obtains the route parameter information of the propagation path , the channel estimation , and sends it over the propagation path from the receiver to the transmitter , the second signal , at the transmitter , the pre- according to the channel estimation the distorted , a signal obtained by pre- distorted , and then sent through the propagation path from the transmitter to the receiver is received at the receiver a signal obtained by pre- distorting .
