摘要： A generalized form of cyclic shift diversity is described for use in an OFDM system with multiple transmit antennas. Multiple cyclic shifts are performed for each transmit antenna and the shifted signals are scaled and summed to form a time-domain data stream for each transmit antenna. A cyclic extension is added to each data stream prior to transmission.

摘要： Cyclic-shift diversity transmission and optional per-subcarrier transmit beamforming within a same time interval (e.g., OFDM symbol interval) takes place. The CSD transmission technique circularly shifts the IFFT output prior to any cyclic prefix insertion and has the effect of putting a subcarrier and antenna dependent phase shift in the effective channel response from each transmit antenna. To properly perform transmit adaptive array (TXAA) transmission within an OFDM symbol interval that is being circularly shifted by the CSD transmission technique, the TXAA weights will account for the frequency domain phase shift created by the CSD circular shift operation.
摘要翻译：发生在相同时间间隔（例如，OFDM符号间隔）内的循环移位分集传输和可选的每副载波发射波束形成。 CSD传输技术在任何循环前缀插入之前循环移位IFFT输出，并且具有将每个发射天线的有效信道响应中的副载波和天线相关相移放在有效信道响应中的作用。为了在通过CSD传输技术循环移位的OFDM符号间隔内适当地执行发射自适应阵列（TXAA）传输，TXAA权重将考虑由CSD循环移位操作产生的频域相移。

摘要： A method for reducing interference within a communication system is provided herein. A receiver (100), and method for operating a receiver are provided. The receiver operates by utilizing a filter bank (103-104) to partition a wide-band signal into smaller sub-bands. Interference suppression takes place individually on the sub-bands (frequency bands) instead of on the wideband signal as a whole. By using interference suppression on smaller sub-bands, interference suppression techniques can be utilized with less computational complexity than when performing interference suppression on the broadband signal as a whole.
摘要翻译：本文提供了一种用于减少通信系统内的干扰的方法。提供接收机（100）和操作接收机的方法。接收机通过利用滤波器组（103-104）来操作，以将宽带信号划分成更小的子带。干扰抑制单独在子带（频带）上进行，而不是作为整体在宽带信号上进行。通过对较小的子带使用干扰抑制，可以比在宽带信号整体上进行干扰抑制时更少的计算复杂度来利用干扰抑制技术。

摘要： In a multiple-input, multiple-output (MIMO) communication system, a method and apparatus for multi-antenna transmission. In accordance with the preferred embodiment of the present invention a reduced number of transmit weight matrices are fed back to the transmitter. Each transmit weight matrix is then applied to a plurality of subcarriers. Because each transmit weight matrix is applied to more than one subcarrier, the amount of weight matrixs being fed back to the transmitter is greatly reduced.
