[Discuss-gnuradio] coding bug in gr-channels/lib/flat_fader_impl.cc

[qin 1921]

I believe there is a bug in file gr-channels/lib/flat_fader_impl.cc, line 67

according to Eq.4 of paper "Improved Models for the Generation of Multiple Uncorrelated Rayleigh Fading Waveforms" published on IEEE COMMUNICATIONS LETTERS, VOL. 6, NO. 6, JUNE 2002, 

that line should be changed from:

         float alpha_n = (2*M_PI*n - M_PI + d_theta)/4*d_N;

to:

       

        float alpha_n = (2*M_PI*n - M_PI + d_theta)/(4*d_N);
