A wireless client device for compensating MU-MAS communication and a dynamic adapting MU-MAS communication system is described. The wireless client device for compensating MU-MAS communication comprises one or more RF units for receiving signals sent by one or more MU-MAS emitter units and down converting the signals to a base band; one or more analog-digital (A/D) converting unit for receiving down converted signals and converting the analog signals into digital signals; a frequency/phase offset estimation/ compensation unit for estimating frequency/phase offset and feeding the information back to the emitter for pre- compensation; one or more OFDM units for removing recycling prefix and rapidly conducting Fourier transform on the digital signals to report signals in frequency domain; a signal channel estimation unit for receiving signals output by the one or more OFDM units during a training period and respondingly calculating signal channel estimation data; and a feedback generating unit for sending the signal channel estimation data to a base station and pre-encoding the signals before the signal is sent to the wireless client device. |
