File Information
Description

The symbols are transmitted using Quadrature Phase Shift Keying (QPSK) 4-QAM. Simulated BER is calculated using ML detection scheme. Theoretical expression is 2*p-p^2, where p is BER for BPSK modulation

Required Products Communications System Toolbox
MATLAB release MATLAB 7.14 (R2012a)

Hi Abdu
If BER in BPSK is p, then from union bound on BER of QPSK for 2-D constellation (x+jy) will be Pr(Error in either x or y) = p+p-p*p

Hi Yogesh K Soniwal

Please can you provide me the reference of your Theoretical expression 2*p-p^2

thank you
