Constant weight codes for multiaccess channels without feedback
Safa Sami Abdul-Jabbar, P. de Laval · 8th European Conference on Electrotechnics, Conference Proceedings on Area Communication · 2003
The design of superimposed codes for the multiaccess OR-channel is considered. The performance of constant-weight codes when used as superimposed codes is investigated. Several constructions for constant-weight codes are compared: affine geometry codes, projective geometry codes, and codes obtained by code concatenation. A comparison to the sphere packing bound and the Johnson bound is made.>
