We propose a simple method for downlink communications based on second order Reed-Muller 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 compressed-sensing. This algorithm allows for low-complexity multiuser detection. ©2009 IEEE.
