Maps a symbol sequence to a binary sequence with binary or gray decoding

Calling Sequence

b = symdemap(x,k[,enc])

Parameters

x:

Input symbol vector (real or complex, depending on the encoding)

k:

Number of bits / symbol

enc:

Specify binary ('b', default), qam ('q'), or phase ('p') encoding

b:

Output binary sequence (a vector of 0 and 1)

Description

Maps a symbol sequence to a binary sequence (sequence of 0 or 1), using one of the following possible encodings:

Example

b = symdemap([-1 1 1 -1], 1, 'b') // NRZ decoding
