Performance Analysis of Cooperative Large MIMO-OFDM System for Downlink and Uplink Mitigation

Judy Simon and N. Prabakaran

The Cooperative Massive MIMO is one in which communication is done by means of clusters by forming virtual antenna arrays. Time Division Duplexing uses a single frequency band which is divided into numerous time slots for both transmission and reception. The multiple input multiple output technology at greater speed converts the data channel of high speed into number of parallel streams. While concentrating on the data rate, there are some drawbacks in wireless parameters. In order to eliminate these drawbacks in the basic parameters like throughput, energy efficiency, power consumption, accuracy in data transmission and mainly crosslink interference while transmitting the data, we have coupled three major concepts into a single project OFDM MODULATION, UPLINK and DOWNLINK MITIGATION and DYNAMIC TDD SYSTEMS. These mitigation techniques had been done only for MIMO so far, and now we used for COOPERATIVE MASSIVE MIMO. The allocation of users for different time slots reduced the number of frequency bands. The parameters are analysed for three types of constellations-16QAM, 64QAM and 128 QAM.
