A Systematic Review of Optimization Paradigms for Enhancing Capacity and Reliability in MIMO-OFDM
Downloads
Communication systems are continued to improve over the time span with main objective to enhance the quality of service (QoS) for multiple users at same time. Multiplexing techniques re used to emerge the set of users into the channel one the account of time or frequency. That made restricted band or disturbs the communication period (time). Alternatively, OFDM channels are made to utilize so-called orthogonality of users to ensure full band full time. The main challenge to this approach is the noise that hits the user payload (signals). In order to overcome the problem of noise, it was necessary to understand the SNR that channel. This paper proposed four optimization algorithms for optimizing the channel capacity using optimum SNR. The Greedy algorithm has made a 90Mbps of channel capacity in lesser convergence time of 0.1 seconds.
