In recent years, the number of portable mobile terminal users is increasing with improvement of the wireless communication environment. In addition, mobile multimedia services also bring the increase of wireless traffic and lack of spectrum resources. As a technique for efficient spectrum use, spectrum sharing receives much attention. It dynamically assigns a spectrum channel from a larger area network such as WiMAX to smaller area networks such as WiFi-based wireless LANs and achieves to increase the total wireless communication capacity of this area. In a case where all providers are cooperative, the spectrum sharing can be realized easily and improve user throughput in average. In another case where providers are not cooperative, some spectrum trading methods based on auction theory had been proposed.

my first big assignment

STM8S - for new member

说明：  BCH码的Berklak-Massey算法，编程比较经典。(BCH code Berklak-Massey algorithm, compare the classic programming.)

HLP A+ Modbus 标准通讯协议格式，上位机发送数据格式，正确时变频器返回数据格式(This bit will be set to logic 1 when the receive buffer has been read and contains no new information. If there is new information available in the receive buffer that has not been read, this bit will return to logic 0. RXBMT = 1 when in Master Mode.)

这是一个去极值滑动窗口数字滤波器算法，在ADC采样的时候可以用这个算法去除脉冲干扰。(This is digital filter algorithm which removes extreme value，and it works just like a sliding window, we can use this algorithm to remove glitches in ADC sampling。)

在matlab下，基于循环前缀的仿真验证源代码，比较详细(In matlab, the simulation based on cyclic prefix for the source code, more detailed)

OFDM waterfilling algorithm

说明：  polar 代码，使用matlab进行仿真，实现了polar代码基本功能，并提供polar基本原理说明(matlab polar simulation)

用于基站定位的RSA算法，采用sdp工具箱求解二次规划问题，增加紧约束条件得到更加精确的MS位置。(The RSA algorithm for base station location uses the SDP toolbox to solve the quadratic programming problem, increasing the tight constraints and obtaining a more precise MS location.)
