Abstract :
This paper presents a simultaneous diversity weights tracking and decoding technique using QRD-RLS based parallel prediction error updating and proposed M-D decoder. This system significantly reduces error propagation in the decision directed array systems with moderate increase in complexity. Computer simulation showed its effectiveness and better performance than that of the existing techniques
