Abstract

Abstract:

In order to suppress both the intra-cell interference and the inter-cell interference in the multi-cell system, a user selection method of the distributed beamforming based on zero-forcing algorithm is proposed. The users are selected with the chord distance between channels, and the base station utilizes these users' channels to implement zero-forcing algorithm and achieve beamforming vectors. Simulations show that under condition of different transmitting antenna number and the users' numbers, the throughput rate of the proposed algorithm becomes superior to the traditional ones'.

Key words: distributed beamforming, zero-forcing algorithm, user selection, chord distance
