—In this paper we present an analytical approach to evaluate the M-QAM symbol error rate (SER) of Alamouti space time coded OFDM direct conversion receivers subject to carrier fr...
Orthogonal frequency division multiplexing (OFDM) system suffers extra performance degradation in fast fading channel due to intercarrier interference (ICI). Combing frequency dom...
Abstract—In this paper we propose a low complexity frequency domain channel estimator for pilot-symbol-assisted (PSA) orthogonal frequency division multiplexing (OFDM) systems in...
In this paper we develop a fine synchronization algorithm for multiband OFDM transmission in the presence of frequency selective channels. This algorithm is based on maximum a post...
