Orthogonal frequency-division multiplexing (OFDM) is a transmission technique that based on many orthogonal carriers are transmitted simultaneously. Channel estimation techniques for OFDM systems, comb-type pilot arrangement, over frequency-selective Rician and time-varying fading channel investigated. The advantage of in estimation, the ability to track variation channel, which main reason inter-carrier interference modelled as an additive white Gaussian noise, leading increase noise level....

Abstract In OFDM systems, time‐varying channels destroy orthogonality between subcarriers causing Inter‐Carrier Interference. To reduce this effect, a Kalman filter, as benchmark, is used for channel estimation, based on comb‐type pilot arrangements of the system. An advantage in estimation ability to track variation caused by Doppler frequency. method has been proposed estimate frequency response (CFR) at locations, then CFR, data subchannels, obtained means interpolation estimates...

Kalman-filter method have been used for the estimation of time-frequency-selective fading channels in OFDM systems, is based on Comb-type pilot frequencies arrangement, channel coefficients that belong to subcarriers are estimated. Then these estimates interpolated using different types interpolations like; Low pass interpolation, Spline cubic interpolation or Linear interpolation. The performances all schemes compared by finding Bit Error Rate where BPSK modulation scheme was used.

Using Reduced Interference Distribution to Analyze Abnormal Cardiac Signal Due the non-stationary, multicomponent nature of biomedical signals, use time-frequency analysis can be inevitable for these signals. The choice and selection proper Time-Frequency (TFD) that reveal exact structure biological signals is vital in many applications, including diagnosis medical abnormalities. In this paper, instantaneous frequency techniques using two distribution functions are applied These...

Mobile communications has become an everyday commodity. In the last decades, it evolved from being expensive technology for a few selected individuals to today’s ubiquitous systems used by majority of world’s population.
