Abstract:

OFDM is a most popular method that used for high data rate in wireless communication. In OFDM combined with antenna arrays at transmitter and receiver side is called MIMO-OFDM and other word MIMO-OFDM system is a consist or combination of the MIMO technique and OFDM technique that use due to increase the diversity gain, time-variant, frequency-selective channels, enhance the system capacity and improve the link reliability high data rate transmission that used for future broadband wireless communication and that are mostly use for avoid Inter-Symbol Interference (ISI) and Inter-Carrier-Interference (ICI). This paper explores physical layer research with IEEE 802.11n standard challenges with different modulation techniques and finds the BER (bit error rate) modulation techniques (BPSK, QPSK, and 712-qam). IEEE 802.11n is a communication standard that provides higher significant throughput and higher date rate.
