Embodiment Construction
[0024] As will be discussed below, the present invention provides a weighted combining method based on the maximum data rate for multi-antenna systems including N-fold spatial multiplexing multi-antenna systems for reducing the transmitted signal energy The subcarriers perform adaptive bit loading. In order to facilitate the understanding of the principles of the present invention, the following will first roughly introduce a typical structure for implementing weighted combining in such a multi-antenna system. The weight generation method of the present invention will be described in detail later, and the weight generation method can be applied to the weighted combination method of the present invention.
