Abstract :
We consider the application of space-time codes in CDMA systems and develop iterative multiuser receivers for CDMA systems with the combination of turbo coding and space-time block coding. According to the orthogonal structure of space-time block codes, algorithms for separate detection and decoding are derived. The performance of the multiuser receivers is analyzed based on the numerical results
