More Information
Summary:In this paper, self-interference (SI) cancellation algorithm based on Space Projection Algorithm (SPA) is proposed for Full-Duplex (FD) Multiple-Input Multiple-Output (MIMO) relays in an indoor wireless communication system. The simultaneous transmission and reception of the same radio signal imply a SI around the relay transceiver. The principal challenge of implementing the FD-MIMO relay is to this interference and increase the relaying capacity. To reach this aims, an efficient algorithm using SPA filters is designed and validated by simulation. The results of proposed method outperform the exiting works in term of BER for the QPSK modulation.
