Abstract

In this paper we propose new schemes combining space diversity and multidimensional constellations, in order to achieve efficient transmission over slow fading channels. The key idea is mapping information bits to points of an N-dimensional signal constellation and project these points on certain sub-spaces. Coordinates from each sub-space are transmitted by independent flat slow fading sub-channels to get both spectral efficiency and diversity. The new transmission schemes are compared by means simulation with well-known systems
