Performance of frequency hopped noncoherent GFSK in correlated Rayleigh fading channels
نویسندگان
چکیده
An analytical treatment of the performance of frequency hopped Gaussian frequency shift keying (GFSK) with differential detection in time-varying Rayleigh fading channels corrupted by additive white Gaussian noise (AWGN) is presented. Closed-form expressions for the bit error rate (BER) as a function of Eb/N0, modulation index, channel Doppler shift, and the timebandwidth product of the pre-modulation filter are derived. A pilot symbol-assisted scheme to lower the error floor caused by frequency hopping is analyzed.

Frequency-hopped multiple-access communications with noncoherent M-ary OFDM-ASK
A noncoherent, bandwidth-efficient modulation scheme is proposed for frequency-hopping multiple-access (FH-MA) networks. The proposed scheme is a combination of noncoherent -ary amplitude-shift keying (NMASK) and orthogonal frequency-division multiplexing (OFDM). Using this scheme will minimize the required data bandwidth. The number of frequency slots available to the users will increase signi...
متن کاملNoncoherent Detection of FSK Signals Transmitted over Linearly Time-Selective Rayleigh Fading Channels
Linearly time-varying fading models are used to investigate noncoherent detection of frequency-shift keying (FSK) signals transmitted over frequency-flat fading channels. The structure of the optimal noncoherent FSK detector is derived and a novel analytical technique is proposed to compute the error performance of noncoherent FSK detectors in fast fading. Error performance results obtained by ...
متن کاملPerformance of Turbo-coded Fh-ss with Partial-band Interference and Rayleigh Fading
In this paper, we investigate the performance of turbo codes when applied to a frequency hopped spread spectrum system with partial-band interference, full-band thermal noise, and Rayleigh fading. We consider two types of channel side information: knowledge that the transmitted bit is jammed or unjammed and knowledge of the instantaneous fading amplitudes. Simulation is performed for coherent a...
متن کاملPerformance of noncoherent turbo detection on Rayleigh fading channels
In this paper, we are concerned with the performance of turbo codes on Rayleigh fading channels when noncoherent detection is employed. Performance of turbo codes with noncoherent detection on AWGN channels has been analyzed by Hall and Wilson. They compared the performance of turbo codes with the achievable information theoretic channel capacity for noncoherent detection on AWGN channels. We, ...
متن کاملMultidimensional Signals with Correlated Frequencies
In this paper, we propose a new transmission technique based on correlated tones associated with noncoherent detection over Rayleigh fading channels. It is shown that the use of multidi-mensional signal alphabets allows to compensate for the performance degradation due to the high correlation between the tones. In this way, the typically low spectral eeciency of noncoherent transmission can be ...
