Abstract(in English) This paper presents the performance of forward link broadband packet TD-OFCDM (Time Division-Orthognal Frequency and Code Division Multiplexing) with iterative channel estimation using both pilot and decision-directed data symbols. Computer simulation demonstrated that, using the iterative channel estimation with the frame structure where the pilot symbols are time-multiplexed at both the beginning and the end of a packet, (1) the required average received E_b/N_0 for average packet error rate (PER) 10^<-2> can be decreased approximately 1.5dB and (2) TD-OF-CDM can still achieve approximately 1.5 fold lager capacity than TD-MC/DS-CDMA (Time Division-Multicarrier/DS-CDMA) at average received E_b/N_0 of 10dB, in a 24-path Rayleigh fading channel with the most delayed path of approximately 1μsec for a single-cell environment.
