چکیده
The conventional Direct sequence DS, and the frequency hopping FH are the common spread spectrum methodologies. The new trend in the spread spectrum communication systems is to use the combined hybrid techniques. The use of a hybrid systems attempt to capitalize upon the advantages of a particular method while avoiding the disadvantages. The paper presents general closed form of the system bit error rate BER assuming noncoherent hybrid DS/SFH employing M-ary frequency shift keying MFSK over Rician fading channel. Moreover; the effect of partial band jamming PBJ on the system performance will be analyzed. Two performance measures are considered; the average BER and system capacity (number of users utilize the system) against SNR for the hybrid DS/SFH is presented. The hybrid DS/SFH performance analysis will be investigated with and without BPJ effect. Moreover; the effect of the rice factor in the system performance will be investigated.

متن کاملSpectral efficiency for a hybrid DS/FH code-division multiple-access system in cellular mobile radio
The spectral efficiency of a hybrid cellular direct-sequence/frequency hopping code-division multiple-access (DS/FH-CDMA) system operating in a Rayleigh-fading environment is examined. In this work, spectral efficiency is evaluated in terms of the theoretically achievable channel capacity (in the Shannon sense) per user, on the condition that this is estimated in an average sense. The analysis ...
متن کاملSlow frequency-hopping multicarrier DS-CDMA for transmission over Nakagami multipath fading channels
A novel multiple access scheme based on slow frequency hopping multicarrier direct-sequence code division multiple access (SFH/MC DS-CDMA) is proposed and investigated, which can be rendered compatible with the existing second-generation narrowband CDMA and third-generation wideband CDMA systems. The frequency hopping patterns are controlled by a set of constant-weight codes. Consequently, mult...

In this paper, multicarrier direct-sequence/slow-frequency-hopping (MC DS/SFH) code-division multiple-access (CDMA) systems are proposed, in which multiple carriers are modulated by the same DS waveform and hopped in frequency according to a random hopping pattern. The receiver dehops the received signal with the same pattern, provides RAKE receivers for each carrier, and combines the outputs w...

In this paper, we introduce the slow frequency hopping (SFH) technique to the multicarrier (MC) code-division multiple-access (CDMA) systems for overlay situations. Using lower chip rate, which results in a narrower spectrum for each carrier and hopping the signal in frequency, the MC direct sequence (DS)/SFH system achieves better performance than the MC DS CDMA system in most cases, especiall...
