`If EbNo is a vector, the output ber is a vector of the same size, whose elements correspond to the different Eb/N0 levels.

Bit Error Rate For Qpsk Matlab Code The alphabet size, M, must be at least 4. Qam Bit Error Rate Equation (1) can be separated into cos and sin terms as follows This can be written as $$ \begin{matrix} s_i(t) = s_{i1}\phi_{1}(t) + s_{i2}\phi_{2}(t) \;\; \rightarrow (3)\\ where,\\ \\ s_{i1} = `
