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.
