turbo码的编解码程序，采用max-log-map算法，简单易用。程序采用QPSK调制，信道为AWGN(turbo code decoding process, using max-log-map algorithm, easy to use. Program uses QPSK modulation, AWGN channel is)

计算源信号和噪音之间的频谱差，用于噪音估计等。(Calculates the average log-spectral distance between CLEAN and NOISY signals)

说明：  Description : This package includes a configurable Simulink model for three different types of DC-DC converters (Buck, Boost and Buck-Boost converters) with a PWM PI controller. The example provided shows a case to boost voltage 5 volts to 25 volts. It can be used to learn DC-DC converters and their control. The model itself also provides an example how to mask a subsystem in Simulink. A HTML and a pdf files are provided to explain the principles of the unform Simulink model for three different types of DC-DC converters. The model does not require other Simulink blocks, such as SimPowerSystems.
