Abstract [en]

We investigate the downlink performance of relay-aided heterogeneous networks (HetNet). An interference cancellation scheme employed at macro base stations is first proposed based on the cancellation of cross-tier interference from the macro base station to small cell users. Then, we derive the expressions of the probability density function (PDF) and cumulative distribution function (CDF) of the received SINRs of both macro and small cell users, and provide the closed-form average bit error rate (BER) and outage probability of the system. Through the derivation and simulation, we show the overall performance improvement of HetNet with interference cancellation in mathematical expression. The numerical results closely follow our analysis.
