Abstract

The invention relates to a method for using antenna to selectively operate the self-adaptive STTD. The receiving terminal comprises following steps: according to the estimation of channel, calculating the SINR of coded STTD in different combination of different emission antennas of each sub-flow; according to the SINR, calculating the total transmission property parameter in said combination; selecting the antenna combination with best total transmission property as present selected combination to attain the selective parameter; according to the SINR, selecting AMC parameters for each emission sub-flow; returning the antenna selective parameter and the AMC parameter via the feedback channel to the sending terminal. And the sending terminal comprises: according to the returned AMC parameter, processing the AMC on the data; processing STTO coding; and according to the returned antenna selective parameter, selecting the antenna combination via which to send the data.

Description

technical field

[0001] The present invention relates to an antenna selection and adaptive transmit diversity technology in a multi-antenna wireless communication system, and more particularly to a method and device for implementing adaptive space-time transmit diversity by using antenna selection. Background technique

[0002] Future wireless communication systems are required to provide higher and higher information transmission rates and communication quality. In order to achieve this goal on limited spectrum resources, multiple antenna technology (MIMO) has become one of the indispensable means used in future wireless communications. In the MIMO system, the transmitting end uses multiple antennas to transmit signals, and the receiving end uses multiple antennas to receive signals. Studies have shown that compared with traditional single-antenna transmission methods, MIMO technology can significantly increase channel capacity, thereby increasing information transmission r...
