Abstract :
Currently most of the terminals for UMTS-FDD implement a simple Rake receiver. This paper shows how the Rake, including despreading and descrambling, could be replaced in a least squares receiver that can be implemented on a Cordic based hardware architecture. The performance in conjunction with the computational requirements of the receiver is widely adjustable. Simulation results show that the performance of this concept can be significantly better than that of the Rake.
