Now-a-days a multi-cell cellular network has drawn broad attention for data rate due to continuously increasing user populations using wireless service. That’s why, recent researches focus on the concept of joint transmission coordinated multi-point (CoMP) transmission which can provide high spectral efficiency for cellular systems. The performance of the Joint Transmission Coordinated Multipoint technique has been analyzed on the basis of signal-tointerference- noise ratio and outage probability variation with both minimum acceptable signal quality and cell radius. In this paper the results are compared with the performance of traditional techniques without coordinated multipoint and obvious improvement has been observed.
