Direct-Sequence Spread Spectrum in a Shadowed Rician Fading Land-Mobile Satellite Channel
نویسندگان
چکیده
The performance of a direct sequence spread-spectrum land-mobile satellite transmission system, using binary phase shift keying (BPSK) modulation, is analyzed. The satellite channel is modeled as having shadowed Rician fading characteristics. The bit error probability is evaluated, considering both the envelope and the phase variation. Assuming a Gaussian approximation for the interference, numerical results are obtained for both spread-spectrum and narrowband land-mobile satellite communication systems with BPSK modulation. A comparison of the two systems is made for light, average, and heavy shadowing.

Implementation of a Real-Time Satellite Channel Simulator
This paper is focused upon implementation aspects of a real-time simulator applicable to narrowband land mobile satellite channels. The satellite channel is mainly affected by shadowing. If a direct signal component exists (line of sight (LOS) conditions), the channel is in a so-called good/clear state and the probability density function (pdf) of the signal amplitude is Rician distributed. The...
متن کاملEffects of Rician Faded and Log-Normal Shadowed Signals on Spectrum Efficiency in Microcellular Radio
An assessment of spectrum efficiency for a microcellular land mobile radio system is presented by considering the desired signal as (fast) Rician fading with (slow) lognormal shadowing and co-channel interfering signals as uncorrelated (fast) Rayleigh fading superimposed over (slow) lognormal shadowing. Spectrum efficiency is defined in terms of reuse distance, Le., cluster size, traffic intens...
متن کاملData-Aided Fading Estimation Technique for Shadowed Mobile Satellite Fading Channels
A novel data-aided fading estimation technique that employs both pilot and data symbols is proposed to significantly reduce the bandwidth redundancy of the pilot-symbol-aided (PSA) systems using receivers with low complexity and latency in the shadowed mobile satellite fading channels. The shadowed mobile satellite fading channels are modeled as the sum of a lognormally distributed direct compo...
متن کاملClosed-Form Performance Analysis of Dual Polarization Based MIMO System in Shadowed-Rician Fading LMS Channels Suresh Kumar Jindal
In this paper, the problem of dual polarization based MIMO Processing in Shadowed-Rician (SR) fading land mobile satellite (LMS) channels is studied. It is shown in literature that polarization is used as a interference rejection method; and, most of the existing analytical results are not in closed-form. In this paper, we derive the closed-form expressions of the moment generating (MGF) functi...

In this paper, the performance of a parallel acquisition scheme is evaluated for a direct-sequence/codedivision-multiple-access (DS/CDMA) system with imperfect power control in a low-earth-orbit (LEO) mobile satellite environment. The acquisition scheme consists of a parallel matched-filter and a FFT processor. The uplink of mobile satellite channel is modeled as a shadowed Rician fading channe...
