Zusammenfassung:This paper proposes a digital intermediate frequency (D-IF) receiver for inter-vehicle communications. Bandpass sampling is employed to lower the sampling rate. Appropriate selection of sampling rate and equivalent digital IF frequency results in a simplified Digital down converter (DDC). Meanwhile, the simplified DDC makes the combination of DDC and the following low pass filter (LPF) possible. This combination reduces the complexity. Unique word (UW) correlation is used to perform frame detection and frequency offset estimation. Finally, a Turbo decoder is employed to provide enough coding gain for combating fading.
