matlab code for ici reduction in ofdm system using kalman filter

ABSTRACT

Orthogonal frequency division multiplexing (OFDM) is emerging as preferred modulation scheme in modern high data rate wireless communication systems. A well known problem of OFDM system is sensitivity to frequency offset between the transmitted and received signals, which may be caused by Doppler shift in the channel or by the difference between the transmitter and receiver local oscillator frequencies. This carrier
frequency offset causes loss of orthogonality between ....etc

Abstract

The demand for high-speed mobile wireless communications is rapidly growing.
OFDM technology promises to be a key technique for achieving the high data capacity and spectral efficiency requirements for wireless communication systems of the near future. This work presents an investigation into methods for maximizing the spectral efficiency of Orthogonal Frequency Division Multiplexing (OFDM) systems. The current standards such as IEE 802.11a in USA and H ....etc

genetic algorithm papr reduction in ofdm matlab code

Abstract

Orthogonal Frequency Division Multiplexing (OFDM) is a form of multicarrier modulation Technique. In this System orthogonally placed subcarriers are used to carry the data from transmitter end to receiver end and has found its way to the high speed wireless and mobile communication world. It has excellent immunity against fading and ISI but its major drawback is peak to average power reduction (PAPR) of the transmitted signal. So many methods are proposed to reduce large PAPR. But ....etc

Abstract

Comparative studies on DWT-OFDM and FFTOFDM systems are presented. The model for DWT-OFDM includes zero-padding and vector transpose for transmitting the OFDM signal. MATLAB simulation commands are also described. The discrete wavelet transform-OFDM (DWT-OFDM) has to satisfy the orthonormal bases and the perfect reconstruction properties to be considered as wavelet transform. Different wavelet families have been used and compared with the conventional F ....etc
