Performance analysis of wide-band M-ary FSK systems in Rayleigh fading channels
نویسندگان
چکیده
Performance analysis schemes for wide-band -ary frequency-shift keying systems with a limiter-discriminator-integrator receiver are presented along with analysis and simulation results for 4-ary and 8-ary systems. The probability distribution of clicks is required for performance analysis and is determined in this letter for Rayleigh fading channels.

Statistic Characteristics of M-ary Fsk Signal in the Presence of Gaussian Noise, Impulse Noise and Variable Signal Amplitude
In this paper we consider a system for coherent demodulation of M-ary FSK signals in the presence of Gaussian noise, impulse noise and variable signal amplitude. These annoyances can seriously degrade the performance of communication systems [1]-[3]. In the paper [4], the performance evaluation of several types of FSK and CPFSK receivers was investigated in detail using the modified moment’s me...
متن کاملBit Error Performance for Asynchronous Ds Cdma Systems Over Multipath Rayleigh Fading Channels (RESEARCH NOTE)
In recent years, there has been considerable interest in the use of CDMA in mobile communications. Bit error rate is one of the most important parameters in the evaluation of CDMA systems. In this paper, we develop a technique to find an accurate approximation to the probability of bit error for asynchronous direct–sequence code division multiple–access (DS/CDMA) systems by modeling the multipl...
متن کاملDifference threshold test for M-ary orthogonal FSK signaling in Rayleigh fading channels
We present the difference threshold test (DTT) for M -ary orthogonal frequency shift keying (FSK) signaling in Rayleigh flat fading channels. The proposed DTT declares an erasure whenever the difference between the largest and the second largest energy detector outputs does not exceed a fixed threshold. We show that the DTT is an approximation of the Bayesian erasure test, but provides almost t...
متن کاملProbability Density Function of M-ary FSK Signal in the Presence of Noise, Interference and Fading
In this paper the receiver for the demodulation of M-FSK signals in the presence of Gaussian noise, intersymbol interference, impulse interference and fading is considered. The probability density function of M-ary FSK signal in the presence of noise, interference and fading is derived. These interferences can seriously degrade the communication system performances. Key-Words: M-ary Frequency S...
متن کاملAn Insight into BER Performance of Reed- Solomon coded M-FSK under AWGN, Rayleigh and Rician Fading Channels
Besides the hardware complexity and hence increased power consumption, M-ary modulation schemes ensure improved performance and bandwidth efficiency. But, in wireless sensor networks where power consumption is a critical issue, it is required to consider non-coherent M-ary schemes together with the possible ways of improving their performance. This paper is a study of BER performance of Reed-So...
