On the performance of a novel synchronous trellis-coded CDMA system for wireless communications Conference Paper uri icon

abstract

  • We introduce a novel modulation signal set defined over a signal space that consists of L Euclidean signal planes, and the synchronous trellis-coded CDMA system based on it. Whereas conventional schemes utilize a limited number of orthogonal sequences due to delay and power control error, this scheme fully and efficiently utilizes the N orthogonal signature sequences (i.e. the processing gain N) such that power and/or bandwidth efficiency is improved. The proposed scheme could be highly adaptable to the dynamic channel conditions, because for a single data rate we can choose the best signal constellation from a multi-planar signal space.
