BER PERFORMANCE OF JOINT POLAR CODED SIGNAL AND MIMO USING MILLIMETER WAVE
There have been active researches worldwide for evolving the next-generation networks such as 5G. The 5G network is predicted to ensure considerable mobile data traffic having large number of wireless connections. This is combined with high energy-efficiency and Quality of Service (QoS). For these reasons, 5G should be exploited the prospect of new developments, including multiple-input multiple-output (MIMO) technology and using higher frequencies such as the millimeter-wave (mmWave) frequency band. Error correction techniques are commonly utilized to reduce transmission error and enhance QoS. In the present work, Cyclic Redundancy Check (CRC) aided polar codes with successive cancellation list (SCL) decoding is used in conjunction with mmWave and MIMO system in order to gain the advantages of these techniques together. The mentioned combined techniques are modeled and simulated to show their performances over different wireless channel models mainly: Additive White Gaussian Noise (AWGN), flat fading, and mmWave indoor fading channel. The results showed that combining polar code with MIMO system improves the Bit Error Rate (BER) performance by at least 6 dB at BER of 10-4 compared to the case where no polar code being used.
