  • Feb 21, 2011 · However I'm new to Rayleigh channel modeling, so I may be missing something. Also, the AWGN channel BER vs SNR curve doesn't look right. For BPSK this curve should match the BER vs Eb/N0 curve (SNR = Eb/N0 for BPSK), which can be generated using "bertool" implemented in Matlab. Thank you for your response. R.Z.
BPSK Modulation IIn phase shift keying (PSK), the phase of a carrier is changed according to the modulating waveform which is a digital signal. It hasone fixed phase when the data is at one level and when thedata is at the other level, phase is different by 180 degree.MATLAB CODE
function BER = AwgnBer(EsN0) x = sqrt(0.1*EsN0); q1 = 0.5*erfc(x); q3 = 0.5*erfc(3*x); q5 = 0.5*erfc(5*x); BER = (12*q1+8*q3-4*q5 - q1*(q1+q3-2*q5)+(q3-q5)*q5)/16; end function f = WeightedAwgnBer(x) weight = 2*x.*exp(-x.*conj(x)); f = weight*AwgnBer(EsN0*x.*conj(x)); end function SER = BlockRayleighFadingBer(EsN0) for ii=1:length(EsN0) SER(ii) = quad(inline('WeightedAwgnBer(EsN0(ii),s)','s'), 0, inf); end end
I'm using the Rayleigh Channel in Simulink but I can't calculate the BER. I always get values near to 0.5 which doesn't make sense (even using high EbNo values). [In this simulink model][1] I found a trick to calculate the BER but I also would like to use delays and attenuation vectors.

  • The Rician fading channel System object models line-of-sight propagation in addition to diffuse multipath scattering. This results in a smaller variation in the magnitude of path gains. To compare the variation between Rayleigh and Rician channels, we make use of a timescope object to view their path gains over time. Note that the magnitude ...

 TL;DR The theoretical BER of an ideal QPSK system is Q ( 2 E b N 0) where E b is the energy per bit and N 0 2 is the two-sided power spectral density of the additive white Gaussian noise channel. The receiver in a standard QPSK system is essentially two BPSK receivers using phase-orthogonal carriers. With a standard matched filter, the signal output in each BPSK receiver has value E b while the noise variance is σ 2 = E b N 0 / 2. The O/S displays X 3TB hard drive said they didn't get the problem. I use windows 7 BPSK channel x64 (unactivated) and have awgn to be accessed from outside a restaurants network.

    Hi, Shannon limit does not depend on a particular BER value. The limit in fact is valid as BER goes to zero. Assume that the BPSK is equi-probable. You only need the code rate and the underlying channel. Any good book on digital communication and coding should tell you what is the minimum Eb/No required for a given code rate on a given channel.
