Ber

Convert::BER is a Perl module for ASN.1 Basic Encoding Rules. SYNOPSIS use Convert::BER; $ber = new Convert::BER; $ber->encode( INTEGER => 1, SEQUENCE => [ BOOLEAN => 0, STRING => "Hello", ], REAL => 3.7, ); $ber->decode( INTEGER => $i, SEQUENCE => [ BOOLEAN => $b, STRING =>...

This program calculates BER curve against SNR for QPSK Modulation in Gaussian Environment.It calculates 100 errors for for each SNR value before calculating BER. This gives a good approximation of BER.I hope this will help students alot.Please feel free to contact me should anyone has any queries.
