PERFORMANCE ANALYSIS OF WIDEBAND CDMA SYSTEMS IN A LOGNORMAL FADING CHANNEL

ABSTRACT

In this letter, the performance of a wideband CDMA system in the presence of Lognormal fading is studied. The wideband CDMA system, modeled using Gaussian Approximation is analyzed on a slow fading Lognormal channel which fades th ....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 ....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 IEEE 802.11a in USA and ....etc

Orthogonal frequency Division Multiplexing (OFDM) is multicarrier transmission technique. OFDM is a communication technique that divides the communication channel into a number of equally spaced frequency bands. A sub carriers a portion of the users information in each band. Each sub carriers is orthogonal (Independent of each other) with every other sub carrier. OFDM efficiently squeezes multiple modulated carriers tightly together reducing the required bandwidth.OFDM was invested in 1960’s, only recently it has recogn ....etc

Abstract
Sampling is the bottleneck for ultra-wideband (UWB) communication. Our major contribution is to exploit the channel itself as part of compressed sensing, through waveformbased pre-coding at the transmitter. We also have demonstrated a UWB system baseband bandwidth (5 GHz) that would, if with the conventional sampling technology, take decades for the industry to reach. The concept has been demonstrated, through simulation ....etc
