MIMO OFDM CHANNEL ESTIMATION USING MATLAB
WebIn wireless communications, channel state information ( CSI) is the known channel properties of a communication link. This information describes how a signal propagates from the transmitter to the receiver and represents the combined effect of, for example, scattering, fading, and power decay with distance. The method is called Channel … WebSep 16, 2024 · Orthogonal frequency division multiplexing (OFDM) is widely adopted in various wireless communication systems due to its remarkable robustness against frequency selective fading [].To resist the multipath effect of the wireless channel, OFDM receivers require precise channel state information (CSI) to demodulate user data more … somerville house willand devon
