Design method of filter coefficient in filter-and-forward relay network

Abstract

The invention aims to provide a design method suitable for a filter coefficient in a filter-and-forward relay network, relates to the technical field of wireless communication relay transmission, and aims to obtain optimal design of the filter coefficient in the filter-and-forward relay network by following a channel capacity maximization principle. The solution of a channel capacity maximization problem is transformed into the solution of a weighted mean square error minimization problem of a receiver in a virtual channel by constructing the virtual channel between a transmitter and the receiver, so that optimal design of the filter coefficient in the whole filter-and-forward relay network is obtained. A good theoretical basis is laid for the design of the filter coefficient, the processing of data and the allocation of resources in the filter-and-forward relay network.

Description

1. Technical field:

[0001] The invention relates to the technical field of wireless communication relay transmission, in particular to a method for designing filter coefficients in a filter forward relay network. 2. Background technology:

[0002] Cooperative beamforming technology is based on the original topological network structure through multi-user cooperation to improve system power efficiency and utilization of wireless spectrum resources. It is a new technology that utilizes geographically dispersed single-antenna wireless relay nodes to achieve space diversity. It solves the problem that a wireless terminal cannot obtain space diversity by installing multiple antennas due to limitations in communication equipment size, transmission power, and system cost. At the same time, through the efficient multiplexing of multi-dimensional resources such as time, space, and frequency in the wireless communication system, cooperative beamforming communication technology can su...
