| Abstract: | The performance of MBOK(M-ary bi-orthogonal keying) systems(including equalization and coding) was analyzed to provide a theoretical tool for ultra wideband modulation system design using information theory.This MBOK system utilizes frequency domain equalization(FDE) for diversity gains and MBOK despreading to reduce FDE residual interference.The residual inter-symbol interference after MBOK despreading in an AWGN(additive white Gaussian noise) is given by an explicit achievable rate expression for MBOK mod... |
