The authors emphasize on transmitter adaption problem of SC-FDE,and propose an ASC-FDE scheme characterized by constant sending info rate and average block power based on PCSI,or CR-ASC-FDE,and theoretically analyze its block average signal to noise ratios employing ZF and MMSE linear equalization methods.Simulations show that the proposed CR-ASC-FDE scheme has much better BER performance than traditional SC-FDE,improves BER performance compared with another ASC-FDE scheme and its OFDM counterpart,and also ...
