BER and Channel Capacity Improvement of MIMO-OFDM and Adaptive MIMOOFDM System By Modulation Technique(QAM)
Journal Title: International Journal of Computer Science & Engineering Technology - Year 2014, Vol 5, Issue 6
Abstract
In the present scenario, with the growing demand for wireless communication in today’s life, along with the parallel rapid growth of digital communication technology, new innovative ideas are coming into existence which needs to be implemented. The main need of any communication system is , basically high speeds of data transmission with higher accuracy and reliability. (Orthogonal Frequency Division Multiplexing) OFDM provides optimistic solutions for achieving high data rates in wireless environment, and because of its opposition towards (Inter-symbol Interference) ISI. (Multiple-Input Multiple-Output) MIMO communication System when integrated with the OFDM system can obtain reliably high data rate transmission over broadband wireless channels. Here, in this paper we have achieved (Bit Error Rate) BER and Channel capacity improvement for MIMO-OFDM and (Adaptive Multiuser Detection) AMUD MIMO-OFDM by the use of M-ary (Quadrature Amplitude Modulation) QAM modulation technique.
