Abstract
The authors show that the linear independence of codewords previously assumed for CV-CCMA to uniquely decode individual transmissions, is not necessary if the number of superimposed codewords is less than the codeword length. It is shown, in fact, that all pairs of two N-tuples of BPSK and QPSK symbols may be simultaneously received by the technique
