Abstract

In this paper, we propose a pilot-signal assisted channel estimation (PSCE) scheme for a multi-carrier modulation (MCM) system where a pilot signal bandwidth is restricted in the subcarrier. In this scheme, at the receiver, the pilot signals of each subcarrier are added up to be inphase at midpoint of pilot-symbol duration, then pilot signal exhibits sharp peak amplitude. Thus channel impulse response can be estimated with a high time-resolution. A simple channel equalization is done using the estimated channel characteristic and BER performance is improved by applying the PSCE scheme to an MCM system under Rayleigh two-path fading condition.
