Abstract

The present invention provides a method and device for combining antennas, wherein the method includes: determining the channel response of each channel through channel estimation, and determining the relationship between the channel and the adjacent channel according to the channel response of the channel and the channel response of the adjacent channel of the channel. The correlation coefficient of the adjacent channel, according to the correlation coefficient, the correlation coefficient of the antenna contained in the channel is obtained by interpolation method, the conjugate of the correlation coefficient of the antenna is the combined weight of the antenna contained in the channel, and the antenna contained in the channel After multiplying the received data by the combination weight, the cumulative value obtained is the received data of the channel. This solution solves the problem of high complexity of the antenna combination operation when the number of antennas is large, and reduces the antenna combination operation. of complexity.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and device for combining antennas. Background technique [0002] In order to resist the impact of fading in mobile communication, diversity reception is one of the effective measures often adopted. In a mobile environment, the fading conditions of multiple signals received through different channels are different. The fading of mobile wireless signals includes two aspects: one comes from the shadow fading caused by terrain, which makes the average power of the received signal fluctuate in a longer space or time; Sharp changes in signal strength over distances. [0003] Receiving mobile wireless signals over a short distance, signal fading is independent in time, frequency, space, angle and polarization. Taking advantage of these characteristics and using corresponding methods can obtain multiple signals that are independent of fading. After obtaining multiple fadin...
