First said the module to include:
Bandpass transmission link: ascending cosine forming source, baseband modulation, pulse shaping, up-conversion, AWGN channel, the frequency conversion, correlator (or matched filter), baseband detection, and obtaining-information
Below is I take a picture:


But the question is:

Sampling on this module is necessary to include, FIR set is a factor of 0.2, order number 160 litres of cosine, not root ascending cosine,
Above the two errors are dimension problem, I thought the dimension of the can, so I then change the sampling rate to the eight, but still have a question,
It's strange strange,
Please eldest brother elder sister to see, help me with my chicken, this dish
PS: I do not have what points... Don't give too much...
