AWGN TESTING - hassantalal - 2010-01-20 03:40:00

HELLO .. I want to test my transmitter for AWGN
.. i have coded mytransmitter and receiver using VERILOG hdl .... kindly if anybody hasverilog code for AWGN .. where i can change SNR values .. and calculate BERfor each SNR.....any suggestions for simulating AWGN and calculateBER.....

Hi Hassan,

You may be interested in our AWGN IP cores coded in Verilog. They are
compact and very accurate, with the PDF error less than 0.2% up to 7.1
standard deviations. The variance of the AWGN output is 1, so to
achieve the desired SNR you need to multiply the AWGN by a constant
(which depends on the signal energy).

You can find datasheets for our Gaussian noise generators on

Regards,

Leendert
