Description
Summary:Analyzes the problem of DFE equalization for a system resulting from the combination of multitone modulation with direct sequence spectrum spreading introduced in Vandendorpe (1994). In order to understand the potential of the system with equalization the authors first study the steady-state behavior of the DFE equalizer for an MMSE criterion. The investigation is carried out for a receiver made of a bank of filters matched to both the symbol shape and the channel, and for a two paths channel. Assuming transmission of BPSK symbols, an exact expression of the bit error probability is obtained.
