Abstract

Abstract: Aiming at problem of lower utilization the authorized spectrum, due to channel quality and transmission power interference, a resource allocation technology was proposed based on the large scale antenna spatial channel controlling. Main lobes beam of multiple antenna beam forming points to the desired user and places the nulls in the interference direction, which can effectively suppress interference to secondary users and ensure that aware spectrum is used. As a result, the utilization ratio of frequency spectrum increased further in the whole system. The simulation results showed the throughput of the proposed method is better than the scheme in the literatures when signal to noise ratio is 5 dB and 10 dB.

Key words: aware spectrum, authorized spectrum, interference, spatial channel controlling
