Abstract

In this paper, space-time block coding (STBC) combining with a novel interleaving technique named block interleaving for convolutionally coded CDMA system is introduced. STBC only works well in slow fading (even very slow fading). If fading is somewhat rapid, STBC can not achieve good performance. The purpose of the scheme presented is to enhance the performance of STBC to resist rapid fading
