摘要: Based on the correlation properties of pseudo-random code in spread spectrum receivers, a novel and unified quantizer model was established, which suitable for both uniform nonuniform quantization. Statistical signal processing technique extreme value theory were employed to obtain analytical formulas optimal quantization corresponding losses. Numerical results quantization, theoretically are achieved using genetic algorithm Monte Carlo simulation, can be used guide engineering design GNSS receivers.
