An algorithm based on beamforming system models and algorithm criteria is simpler than the traditional eigen-value decomposition method. It also can overcome the problem of the large complexity and system delay in the process of beamforming. According to the TD-LTE protocol, an uplink signal source and model is constructed. And then, the beamforming weighting factor is obtained by constructing the complete beamforming link. In the multipath fading channel, the traditional eigen-value decomposition algorithm based on the QR factorization (a method of orthogonal matrix triangularization) and simple algorithm is simulated. The results indicate that the simple EBB algorithm can reduce the complexity by 1/60 and keep the same or similar precision with the traditional algorithm.
