2.2 Transmission model with channel fading The immediate effect of the phase error is degradation of the detection performance of coherent systems, which, to some extent, may be mitigated by sending a pilot tone [12] with the transmitted signal. In this case the receiver operates with the unmo...
Destructive interference may also cause extended depreciation of the received signal, leading to fading. The overall effect on the signal is thus dependent upon the amplitude and the relative phase of each individual component of the multipath signal. To understand the phenomena of multipath, it is...

The visualization also shows the delays and magnitudes of the underlying fading path gains (pink stembars) clustered around the peak of the impulse response. Note that the path gains do not equal the AveragePathGains property value because the Doppler effect causes the gains to fluctuate over ...
In this paper, performance of STBC-OFDM is analyzed under different constraints in Rayleigh fading channels. We have studied the effect of modulation order, antenna selection techniques, slow and fast fading conditions and power conditions on the performance of STBC-OFDM.Gunjan Manik...
This kind of multipath fading is often referred to as narrowband fading, or frequency-flat fading. To observe the effect, we now reduce the signal bandwidth from 10M b/s (5M sym/s) to 1M b/s (500K sym/s), so the delay span (0.8 microseconds) of the channel is much smaller than ...
h=(1/sqrt(2))*randn(1,3)+j*(1/sqrt(2))*randn(1,3) In phase and quadrature components have Gaussian distribution with zero mean, and variance 0.5. Reply Leave a Reply
In mobile communications there are problems due to multipath fading. An adaptive array antenna has been studied as a countermeasure to compensate for signal distortion due to fading because an array antenna can reduce multipath interference by using antenna directivity in the space domain. This paper...
As discussed in Chapter 2, a radio channel subject to time dispersion, with the transmitted signal propagating to the receiver via multiple, independently fading paths with different delays, provides the possibility for multi-path diversity or, equivalently, frequency diversity. Thus, multi-path propag...
