ABSTRACT:
The present invention concerns a sphere decoder for maximum likelihood receiver intended to receive M-PPM-M′-PAM symbols at M modulation positions and at M′ amplitude levels from a plurality P of sources. The sphere decoder uses a Schnorr-Euchner type enumeration adapted to classify the points of a multidimensional PPM-PAM modulation.
