Time selectivity of multipath channels introduces significant inter-carrier interference (ICI) in OFDM systems demanding high levels of mobility and capacity. In this paper, a piecewise channel approximation is presented for improving the structure o

Channel state information (CSI) is defined as the signal-to-noise ratio (SNR) for a sub-carrier position. In white noise channels it is proportional to magnitude of the channel frequency response (CFR). However, if the channel introduces frequency se

In order to improve receiver performance in multipath channels, signal-to-noise ratio (SNR) should be maximized. In this paper, we propose and analyze several noise mitigation techniques for orthogonal frequency division multiplexing (OFDM) receivers

In this paper, we analyze and compare the performance of OFDM receivers with blanking, clipping and combined blanking-clipping nonlinear preprocessors in the presence of impulsive noise. Closed-form analytical expressions for the signal-to-noise rati

A simple method of improving orthogonal frequency division multiplexing (OFDM) receiver performance in an impulsive noise environment is to precede a conventional OFDM demodulator with blanking nonlinearity. This method is widely used in practice sin

Orthogonal frequency division multiplexing (OFDM) is a technique used for terrestrial digital video broadcasting (DVB-T) and many other modern applications. The longer OFDM symbol duration provides an advantage in a presence of weak impulsive noise,

In order to improve receiver performance in multi-path channels, signal-to-noise ratio (SNR) should be maximized. Therefore, in this paper, we propose a channel impulse response analyzer (CIRA)-based adaptive methods1 which can effectively reduce the

Most of the performance studies devoted to the analysis of multicarrier systems in the presence of nonlinear distortion assume that the multicarrier signal can be modeled as a random Gaussian process regardless of modulation format, guard interval du
