Method and System for Switching Antennas during Transmission Time Intervals in OFDMA Systems
摘要：
A method and system switches antennas in an orthogonal frequency division multiplexed access (OFDMA) wireless communication system while transmitting symbols. Each symbol includes a cyclic prefix and a block of data signals. The symbols are transmitted during a first portion of a transmission time interval (TTI), from a first antenna. Then, the RF chain is switched to a second antenna to transmit the symbols, and in which the switching is performed substantially between transmitting two consecutive transmitted symbols.
摘要（中）：

方法和系统在发送符号的同时在正交频分复用接入（OFDMA）无线通信系统中切换天线。 每个符号包括循环前缀和数据信号块。 在传输时间间隔（TTI）的第一部分期间，从第一天线发送符号。 然后，将RF链切换到第二天线以发送符号，并且其中基本上在发送两个连续发送的符号之间执行切换。
