| Abstract(in English) | This paper proposes complexity reduction techniques for parallel blind demodulators in the presence of intersymbol interference due to time-varying frequency selective fading. In mobile radio communication, narrowband data transmission causes fast time-varying fading normalized by symbol rate and demodulators suffer from severe error floor. First, this paper shows why demodutators suffer from burst errors, evaluating occurrence of burst errors due to the timing ambiguity of the blind demodulator. Next, this paper proposes timing slip detection schemes in order to combat the timing ambiguity and proposes novel parallel blind demodulation techniques preparing several initial estimated channel impulse responses. Finally, computer simulation confirms that the proposed parallel blind demodulators with smaller expanded trellis memory have better performance than the conventional one. |
