This paper the performance of two precoding methods for Co-ordinated Multipoint (CoMP) Downlinktransmission systems, Singular value decomposition and the QR decomposition is being studied and finally compared. Inthis we propose to study the performance of the two precoding scheme using Rayleigh fading channel. The Bit Error Rate(BER) performance of CoMP system is studied through different algorithms for improvement of system performance. Theimprovement of BER performance is based on SVD and QRD algorithm. Basically these precoding schemes areadopted from the multiple input multipoint output (MIMO).Computer simulations show that, in the case for differentMIMO like 2x2, 4x4, 8x8 QRD performs better than SVD but at the cost of computational complexity. MATLABsimulations are used to evaluate the performance of the studied precoders in terms of QRD and SVD for CoMPDownlink systems with MIMO.
