Bit Error Rate Matlab
of bits that have errors relative to the total number of bits received in a transmission, usually expressed as ten to a bit error rate example negative power. For example, a transmission might have a BER of 10 to the minus 6, meaning that, out of 1,000,000 bits transmitted, one bit was in error. The BER is an indication of how often a bit error rate vs snr packet or other data unit has to be retransmitted because of an error. Too high a BER may indicate that a slower data rate would actually improve overall transmission time for a given amount of transmitted data since the BER might be reduced, lowering the number of packets that had to be resent. A BERT (bit error rate test or tester) is a procedure or device that measures the BER for a given transmission.

In this post, we will derive the theoretical equation for bit error rate (BER) with error rate definition Binary Phase Shift Keying (BPSK) modulation scheme in Additive White Gaussian error rate formula Noise (AWGN) channel. The BER results obtained using Matlab/Octave simulation scripts show good agreement with the

derived theoretical results. With Binary Phase Shift Keying (BPSK), the binary digits 1 and 0 maybe represented by the analog levels and respectively. The system model is http://whatis.techtarget.com/definition/bit-error-rate-BER as shown in the Figure below. Figure: Simplified block diagram with BPSK transmitter-receiver Channel Model The transmitted waveform gets corrupted by noise , typically referred to as Additive White Gaussian Noise (AWGN).
