Abstract :
A wireless multimedia network using a novel channel equalizer on a TDD CDMA/TDMA scheme is proposed. The uplink employs a CDMA scheme to transmit low speed human interface signals, and the downlink employs a TDMA scheme to transmit high speed signals including video and images. The control signals for equalization are calculated by using the output of the matched filters of the CDMA receiver. Theoretical analysis has been carried out to evaluate the BER performance. Numerical results show that a low BER of less than 10-6 is achieved for the downlink by employing the proposed channel equalizer
