Polar Coded Adaptive Data Transmission in an Indoor mmWave Scenario

Communications at millimeter wave (mmWave) band is more vulnerable to blockages due to the ultra-high frequency. Taking this effect into account, this paper considers a point-to-point communication system in an indoor mmWave scenario. A two-state-channel (TSC) model, i.e., line of sight (LoS) state and non line of sight (NLoS) state, is exploited to describe the blockage effect. Leveraging the nesting property of polar codes, an adaptive data transmission scheme is proposed to achieve higher capacity in the TSC model. Numerical results verify the good performance of the proposed scheme.
