one other question about channel coefficients:
suppose a Rayleigh fading channel with just one path between transmitter and receiver (a frequency flat fading). Is channel coefficient for this single path Complex or Real.
off course I know that if the channel coefficient is complex, then it's...
hi
in wireless communication when T > T_D Doppler effect leads fast fading, where T is symbol duration and coherence time is T_c = 1/f_D.
f_D has the maximum value of 300 Hz, so T_c has the minimum of 3 ms. so Doppler phenomena only affects systems with symbol rate below 300 sym/sec.
thus in...
Hi I have a related question
suppose a 3-path Rayleigh Frequency Selective fading channel which coherence time is T_c. does it mean that within a T_c time duration, channel coefficients are constant?
and is there any model for changing channel coefficients with time?
Hi
I want to simulate a new modulation scheme named DCSK for Differential Chaos Shift Keying.
this modulation does not use sinusoidal signals as base signals, but uses chaotic signals (a noise-like signal).
for each symbol to be sent, we have a signal consisted of N real samples. I want to...
