Abstract
A detector for multirate WCDMA systems based on an adaptive signature method was designed and implemented. Based on an adaptive algorithm, we considered two multirate schemes - the low rate detector and the high rate detector - for variable spreading factor systems. Numerical simulations compared the both multirate schemes in WCDMA scenarios. Hardware complexity of these two multirate schemes was analyzed. Hardware implementation was targeted on Virtex II Pro technology to maximize the number of simultaneous users on one FPGA component.
设计并实现了一种基于自适应签名方法的多速率WCDMA信号检测器。基于自适应算法，我们考虑了两种多速率方案——低速率检测器和高速率检测器——用于可变扩频因子系统。数值模拟比较了两种多速率方案在WCDMA场景下的性能。分析了这两种多速率方案的硬件复杂度。硬件实现以Virtex II Pro技术为目标，以最大限度地增加一个FPGA组件上的同时用户数量。
