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.

This is GPS Matlab findPreambles finds the first preamble occurrence in the bit stream of each channel. The preamble is verified by check of the spacing between preambles [6sec] and parity checking of the first two words in a subframe. At the same time function returns list of chAnnels, that are in tracking state and with valid preambles in the nav data stream.

This example sets up the PLL in x10/2 mode, divides SYSCLKOUT by six to reach a 25Mhz HSPCLK (assuming a 30Mhz XCLKIN). The clock divider in the ADC is not used so that the ADC will see the 25Mhz on the HSPCLK. Interrupts are enabled and the EVA is setup to generate a periodic ADC SOC on SEQ1. Two chAnnels are converted, ADCINA3 and ADCINA2.

This experiment uses the Blackfi n BF533/BF537 EZ-KIT to run a simple FIR fi lter on stereo chAnnels at a sampling frequency of 48 kHz. The CYCLE register is embedded in the main program ( process_data.c) to benchmark the time needed to process two FIR fi lters. A background telemetry channel (BTC) is set up to display the cycle count.
