Abstract :
This paper presents an analytical model to evaluate the performance of the multistage multicarrier demultiplexer/demodulator (M-MCDD) in the presence of quantization noise as well as additive white Gaussian noise (AWGN) and adjacent channel interference (ACI). The analysis has been limited to halfband filter coefficient quantization. A procedure for numerical computation of the probability of bit error based on the Gram-Charlier series technique is introduced
