In this Paper the exact expressions for the Symbol Error Probability (SEP) of Hybrid Selection/Maximal Ratio Combining wireless systems for M-ary QAM are derived and analyzed in multipath fading environment. Independent Rayleigh fading diversity branch is assumed for analysis with equal Signal-to-Noise Ratio averaged over the fading channels and coherent detection of M-ary Quadrature amplitude ...

In this study, Enhanced Data rate for GSM Evolution (EDGE) mobile communication system is analyzed and modeled assuming to operate in both Additive White Gaussian Noise (AWGN) channel and Rayleigh fading channel. A MATLAB software package is developed to simulate extensively the EDGE system. The system analysis takes into account channel coding, modulation type, interleaving and burst building,...

In this paper, we analyze the Bit Error Rate (BER) performance of Golden coded Multiple-Input Multiple-Output Orthogonal Frequency Division Multiplexing (MIMO-OFDM) system over Rician multipath fading channel. We also compare the performance of the MIMO-OFDM system using Golden code in Rayleigh and Rician multipath fading channels. We discuss the effects of the presence of line-of-sight (LoS) c...

This paper represents the MIMO channel capacity over Rician fading, Rayleigh fading and Nakagami fading channel. Here Rician fading model employs a zero-mean stochastic sinusoid as the line-of-sight component. This paper offers analyses and simulations to the behavior of MIMO system and its expected capacity for various channel distribution under flat fading. Several types of distributions (Ric...

PN code tracking is one of the most important factors that affect the performance of spread spectrum receivers. It is desirable to maintain PN code tracking for a long period of time and with high accuracy. This paper presents a non-coherent digital delay-locked loop (DLL) for code tracking in direct-sequence spread spectrum (DS-SS) systems. The proposed technique utilizes three non-coherent co...

This paper reveals a previously-unknown infinite linear combination of Gamma distributions with simple coefficients for the symbol-detection signal-to-noise ratio (SNR) in multiple-input/multiple-output (MIMO) communications employing spatial multiplexing and zero-forcing detection (ZF), whereby the intended (detected) and interfering symbol streams experience correlated Rician and Rayleigh fad...

Following a unified analytical framework, the bit error rate (BER) of several coherent and non-coherent binary modulation schemes are derived for a switched diversity system. The two variants of switched combining (SWC) that have been investigated are switch and stay combining (SSC) and switch and examine combining (SEC). For channel modelling, at first a simple slow flat fading channel is assu...

In this paper, a Colored Rayleigh Fading Noise Generator (CRNG) model adapted to hardware implementation in FPGA circuit is developed for mobile communication channel emulation. To speed up Rayleigh Noise generation the presented design is based on a reduced complexity 2 order AR filter applied to a High accuracy Box-Muller based White Gaussian Noise. The statistical properties of the designed ...
