Guided MAC to Enhance Quality of Experience of Video Data Transmission over Massive MIMO

Abstract

Abstract Massive MIMO (M-MIMO) system contains hundreds of antennas at base station to achieve large gains in spectral-efficiency when compared with conventional MIMO technology. High speed and Quality of Experience (QoE) of video data over wireless communication has always been a challenge for the researchers due to scarcity of the bandwidth, fading and interference. Noisy channels corrupt the transmitted video and results in poor QoE of at the receiver. Therefore, to maintain the QoE of the video, it is highly desirable to identify noisy channels and avoid transmission over them. In the proposed approach, the channels are categorized into two categories: good or bad. If SINR value is greater than threshold value a channel is good otherwise bad. A Guided MAC layer (GMAC) protocol is designed to transmit the video data over good channels only and to discard the transmission over bad channels.
