Mapper for Arbitrary Signal Constellations 1.0

%SIGMAPPER Mapper% H = SIGMAPPER(CONSTELLATION, MAPPING) constructs a SIGMAPPER object H to% map a bitstream to the points of a signal constellation. The signal% constellation is specified by the vector CONSTELLATION which contains% the real or complex signal points. The mapping is done according to% the vector MAPPING. The vectors CONSTELLATION and MAPPING are usually% generated by using MATLAB Modem Modulation Modem., but in general% any constellation and any mapping can be used.%% A SIGMAPPER object is equipped with one function:% - SIGMAP (type "help sigmapper/sigmap" for detailed help)%% Input: CONSTELLATION [1xM]% MAPPING [1xM]%% Output: H [1x1]Example of use:h = sigmapper(constellation,mapping); % generate handle to sigmapper objectu = randi([0 1],block_size,1); % generate bit stream of length block sizex = modulate(h,u); % do mappingThe vector x contains the real or complex signal points.## important: Before you can use these files you have to compile the mex-file mex_sigmap.cpp, which can be done by executing the file compile_mex_sigmap.m. There is a test file included as well.
