Dear all,
First What I wanna do is generate a S(x) 16 M-ary symbol use PPM. Then push
S(x)
through a filter which is the impulse response. and then add gaussin noise
after transmitted. at the receiver side, through the filter again and get the
received symbol to find the UBPe(Union Bound Error Probabilities) of the Signal.
It is a simple procedure to describe however...
My problem is
1. How to generate the random symbol? It should be a signal which has only
one pulse in a specified interval. I found the randerr function can do this job
while after I got the Ns*M matrix I do not know how to convolution it with the
impulse.
2.how to get the UBPe? Should I compare the received symbol to the
original one and find the error probabilities?
Regards
