There a t least five Request for Enhancement s (RFE) in the JavaSoft bug database related to Mouse Wheel support in Java. One of the RFE s BugID #4202656 has 281 votes from developers requesting Sun for a fix. Sun has finally agreed to support this feature in JDK 1.4 codenamed Merlin accroding to the BugID #4289845 in its bug database.
In this project we analyze and design the minimum mean-square error (MMSE) multiuser receiver for uniformly quantized synchronous code division multiple access (CDMA) signals in additive white Gaussian noise (AWGN) channels.This project is mainly based on the representation of uniform quantizer by gain plus additive noise model. Based on this model, we derive the weight vector and the output signal-to-interference ratio (SIR) of the MMSE receiver. The effects of quantization on the MMSE receiver performance is characterized in a single parameter named 鈥漞quivalent noise variance鈥? The optimal quantizer stepsize which maximizes the MMSE receiver output SNR is also determined.
