WebJun 26, 2024 · Abstract: We study the problem of unsourced random access (URA) over Rayleigh block-fading channels with a receiver equipped with multiple antennas. We employ multiple stages of orthogonal pilots, each of which is randomly picked from a codebook. In the proposed scheme, each user encodes its message using a polar code and appends it … WebThe performance of MIMO system can be improved by using multiple antennas at transmitting and receiving side to provide spatial diversity. In this paper, the effects of the number of transmit and receive antennas on the performance of MIMO system over AWGN and Rayleigh fading channels with ZF receiver is analyzed.

WebI What is the outage probability of a block fading Rayleigh channel with average SNR = for a transmission rate r? P out = Pr(log(1 + ) Webfeatures of the practical slowly-varying fading channels. In a block-fading channel a codeword spans a finite number B of independent fading blocks. As the channel relies on particular realizations of the finite number of independent fading coefficients, the channel is non-ergodic and therefore not information stable [3], [4].
