the shannon's law
R=BWlog2(1+C/N)
in a PSSS system
Is R the symbol rate here?
and BW is still the channel bandwidth?

Thanks!
 

Re: symbol rate, BW?

The Shannon-Hartley capacity theorem computes the system capacity (C) of a channel with additive white Gaussian noise (AWGN). You need to realize this theorem only sets a theoretical limit on transmission rate, not error probability. It is:

C = W * log2(1 + S/N)

S/N is the average signal-to-noise ratio and W (hertz) is the bandwidth of the channel. Because the log is base two, C is in bits/second, not symbols/sec.
