Computes Bit Error Rate (ber) for Additive White Gaussian Noise (AWGN) channel
Waveform object (see wf_init)
Eb/No, in dB (a vector or a single value)
Waveform type ('ask','qam','psk','qpsk','dpsk','oqpsk','fsk',...)
Number of symbols used in transmission (default is 2). It is integer power of 2 and one among 2,4,8,16,32
'c' (coherent demodulation) or 'i' (incoherent)
Resulting Bit Error Rate vector (one value for each valeu of Eb/N0)
When symbols are transmitted over communication channel having additive white gaussian noise then probability of error for the received symbols is given by this function. For case of 'fsk' correlation among the carriers and method used for detection at receiver which is coherent or noncoherent also needs to be specified. This function returns an array having same size as the size of array containing Eb/No values.
