AWGN,SNR,Eb/No

Started by Unknown August 19, 2003
Hi everyone,

I want to simulate a W-CDMA downlink channel. To evaluate the performance I want
to plot the BER over the Eb/No.
The matlab y=awgn() function adds gaussian noise to the spreaded and oversampled
transmitted signal. So how can I scale the noise power for oversampling and
spreading?

how is the relation between SNR and Eb/No?

Thanks very much,

Stefan
