Webwhile RIS yields no signiﬁcant reﬂect beamforming gain under Rayleigh fading, it does yield an array gain which becomes signiﬁcant in noise-limited systems. Under Rician fading, however, the RIS phase-shifts appear explicitly in the deterministic equivalents and therefore RIS yields both an array gain and reﬂect beamforming gain ... WebApr 13, 2024 · In this code, we drive the Capacity of a MIMO system over Rayleigh fading channel with different number of transmit and receiver antennas. For each setting of a MIMO channel, after calculating the singular values of the channel matrix, transmit power is distributed based on water-filling algorithm. pony trap for sale
