A comparison of slow-frequency-hop and direct-sequence spread-spectrum packet communications over doubly selective fading channels
نویسندگان
چکیده
In this letter, the performance is compared for slowfrequency-hop and direct-sequence spread-spectrum packet communication systems of similar complexity with doubly selective fading channels characterized by several different multipath delay profiles and Doppler spreads. The delay profiles are chosen to reflect experimental measurements of mobile-radio channels, and the Doppler spreads are chosen to represent the range of carrier frequencies and vehicle speeds encountered in common mobile communication systems.

Analysis & Design of a Frequency - Hopped Spread - Spectrum Transceiver for Wireless
Personal Communications Services (PCS) require low-power radio technologies. One such transceiver architecture employing frequency-hopped spread spectrum techniques is described. Low power and robustness are two keys to a wireless personal communications device. A frequency-hopped code-division multiple access (CDMA) scheme is chosen over other multiple access methods because it provides an inh...
متن کاملPerformance of soft metrics for convolutional coded asynchronous fast FHSS-MA networks using BFSK under Rayleigh fading
Performance of robust soft decoding metrics is examined for use in convolutional coded asynchronous fast frequency-hop spread-spectrum multiple-access networks using binary frequency-shift keying under Rayleigh fading channels. For comparison, maximum-likelihood metrics based on a Gaussian approximation are derived. Significant gains are observed compared to hard decision decoding by using appr...

A modified multicarrier (MC) direct-sequence code-division multiple-access (DS-CDMA) system has been proposed for use over slow multipath fading channels with frequency selectivity in the reverse link transmission of a cellular network. Instead of transmitting data substreams uniformly through sub-channels, data substreams hop over subchannels with the hopping patterns adaptively adjusted to th...
متن کاملPerformance comparison of FFH and MCFH spread-spectrum systems with optimum diversity combining in frequency-selective Rayleigh fading channels
In this letter, the performance of frequency-hopping spread-spectrum systems employing noncoherent reception and transmission diversity is analyzed for frequency-selective Rayleigh fading channels. Two different types of transmission diversity systems, a fast frequency-hopping (FFH) system and a multicarrier frequency-hopping (MCFH) system, are investigated. In order to combine received signals...
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...
