| 摘要 | Systems and methods for wireless communication in a system including a transmitter, a receiver, and a plurality of propagation paths formed between the transmitter and the receiver which are capable of carrying a signal transmitted by the transmitter to the receiver. The method includes transmitting a first signal from the transmitter to the receiver via a propagation path of the plurality of propagation paths, receiving the first signal at the receiver, performing a channel estimation of the first signal to obtain path parameter information of the propagation path, sending the channel estimation from the receiver to the transmitter via the propagation path, predistorting a second signal at the transmitter according to the channel estimation, transmitting the predistorted signal from the transmitter to the receiver via the propagation path, and receiving the predistorted signal at the receiver. | ||

| 主权项 | 1. A method for wireless communication in a system including a transmitter, a receiver, and a plurality of propagation paths formed between the transmitter and the receiver which are capable of carrying a signal transmitted by the transmitter to the receiver, the method comprising: transmitting a first signal from the transmitter to the receiver via a first propagation path of the plurality of propagation paths; receiving the first signal at the receiver; performing a channel estimation based on the first signal to obtain path parameter information of the first propagation path; sending the channel estimation that includes the path parameter information from the receiver to the transmitter via the first propagation path; predistorting a second signal at the transmitter in a time domain, a frequency domain, and a spatial domain, according to the channel estimation based on the first signal; transmitting the predistorted second signal from the transmitter to the receiver via the first propagation path; and receiving the predistorted second signal at the receiver. | ||
