Abstract: We propose a simple method for downlink communications based on second order ReedMuller sequences which generalize the Walsh sequences that are used in orthogonal CDMA. In our approach, coding occurs at the chip level (i.e. we use a spreading factor of 1) and different users are not orthogonalized. Our decoding algorithm is borrowed from work on fast reconstruction of signals for compressedsensing. This algorithm allows for lowcomplexity multiuser detection. ©2009 IEEE.
