Blind demodulation
WebBlind Demodulation for DS-CDMA transmission over frequency selective channels Vincent Le Nir, Toon van Waterschoot, Jonathan Duplicy, and Marc Moonen I. ABSTRACT In … Web(CFO). The blind demodulator’s performance in AWGN and a perfect channel is evaluated where it improves using a greater number OFDMA Downlink (DL) symbols and increased Cyclic Prefix (CP) length. Performance in a channel with a single multi-path interferer is also evaluated where the blind demodulator’s performance is degraded.
