This letter introduces a generalized version of Kay's estimator for the frequency of a single complex sinusoid in complex additive white Gaussian noise. The Kay estimator is a maximum-likelihood (ML) estimator at high signal-to-noise ratio (SNR) base

This paper treats the problems of digital TV terrestrial broadcasting in presence of co-channel interference from analogue TV services. The channel capacity is calculated for the optimum distribution of the transmitted power. An OFDM scheme is presen

Performance of Maximum Likelihood Sequence Estimation (MLSE) in receivers highly depends on the reliability of the channel parameters estimation. Traditionally, the channel parameters are estimated based on the tentative decisions before the MLSE det

This paper presents pulses of finite duration for use in orthogonal frequency division multiplexing (OFDM) using offset QAM modulation. In such a system the pulses will overlap in both frequency and time without intersymbol or interchannel interferen

A carrier frequency offset (CFO) or a time varying (fading/Doppler spread) channel in an orthogonal frequency division multiplexed (OFDM) system will create interbin interference (IBI). IBI causes decreased SNR and increased symbol error rate (SER).

This article introduces a generalized version of Kay's (1989) estimator for the frequency of a single complex sinusoid in complex additive white Gaussian noise (AWGN). Kay developed a maximum likelihood (ML) estimator based on differential phase meas

In this paper, Maximum-Likelihood Sequence Estimation (MLSE) for OFDM is derived together with a corresponding upper bound on probability of error. The error bound of the MLSE is used to assess the performance of an OFDM system with a two-path channe
