Abstract :
A novel transmitter for MC-CDMA has been proposed and excellent increase of user capacity has been confirmed by the numerical simulation. It became clear that 8 elements array for space diversity and 16 subcarriers for frequency diversity provide efficiency of 12 bit/s/Hz in case of Walsh-Hadamard sequence and MMSEC. We are to examine methods of estimating the response vector.
