这是一个学习Symbian的ListBox的好例子,我也是看学个学会的(This is a learning Symbian a good example of the ListBox, I also watch a Institute of Science)

极化码基础方法仿真代码，并附外文解释文档(Polarization code basic method simulation code, with foreign language interpretation document.)

Photovoltaic systems, solar thermal systems based on knowledge training(PVSystem)

HDLC控制协议中CRC校验码算法代码，为CRC16，Verilog语言(HDLC Control Protocol Code in the CRC checksum algorithm code for CRC16, Verilog language)

1. 关于无线信道的多普勒谱，请回答以下问题： (1) 在某些无线信道中，多普勒频移会引起无线信道输出信号的混叠。请清楚的描述产生混叠的各种原因； (2) 无线信道中的多普勒谱有一种经典谱(classic spectrum)，请解释产生这种谱形状的机理； (3) 请用S-function产生一单径瑞利信道，其多普勒谱为经典谱，其中移动速率为120km/h。并请回答：证明自己用计算机产生的经典谱是正确的可能方法。 (Doppler spectrum of radio channel 1, please answer the following questions (1) In some wireless channel, radio channel Doppler shift will cause the output signal aliasing. Please clearly describe aliasing for various reasons )

c语言实现的lwm2m协议，程序是可以直接编译通过的，主程序在src的lwm2mclient.c中(The lwm2m protocol implemented by C language can be compiled and passed directly. The main program is in lwm2mclient.c of src.)

DOA估计的算法，其中包括Music算法、空间平滑Music算法、Root-Music算法、ESPRIT算法MVDR（最小方差无失真）算法等，便于比较(DOA estimation algorithms, including algorithms Music, Music spatial smoothing algorithm, Root-Music algorithm, ESPRIT algorithm MVDR (minimum variance distortion) algorithm, to facilitate comparison)
