超宽带通信系统发送使用BPSK调制 适合于CM3和CM4信道-UWB communication system using BPSK modulation for sending CM3 and CM4 channel

Cortex-M4的内核资料，英文版，对于NVIC介绍的比较详细，为更好的学习CM4为内核的MCU做准备了。-The Cortex-M4 core information in English, a more detailed introduction for NVIC, the kernel of the MCU to prepare for a better learning CM4.

这是一个基于802.15.3a的S_V模型，时间按双泊松分布，幅度双指数分布，可更改CM1/CM2/CM3/CM4的参数，得到四种不同情况下的多径分布-This is a model based on 802.15.3a the S_V time by double Poisson distribution, amplitude double exponential distribution, the parameters can be changed CM1/CM2/CM3/CM4 obtai

cm4加解密工具，两种模式，ESB,CBC 可以参考使用(CM4 encryption and decryption tool)
