【Abstract】 Studies the design of decision-feedback multi-user (DFM) detector with RAKE receiver which improves a common DFM detector based on block-decorrelation and optimizes the overall capacity of the system on such as computatin speed of detector, economic use of memory, and reduction of error probability with the influence imposed by the power of user on the decision feedback and the adoption of RAKE receiver thchnology, and concludes that the new receiver is better than DFM detector without RAKE and decorrelator.更多还原
