ABSTRACT This paper proposes a coordinated multi-point (CoMP) scheme for improving wireless communication performance. The signal from the transmitter is distorted by various reasons such as inter-cell interference (ICI), power reduction, incorrect channel estimation. In order to improve uplink communication performance, the proposed scheme applies the spatial phase coding (SPC). In this paper, two base stations and one user equipment are considered. The two base stations receive at same time from user equipment. By the SPC precoding, the receiver has high bit error rate (BER) performance and throughput. Therefore, proposed scheme reduces the problems of user equipment in the edge of cell coverage. |
