A Minimum Bit Error Rate Loading Algorithm for OFDM Systems Applications of BIT in DFCS

Demultiplex filter ( usually refers to bandpass filter) is a significant part of DFDS, while the flat frequency response and linear phase characteristic in the passband of the FIR filter make it the best choice for the system.
