四阵元理想情况下情况下，来波方向为30度时，波束赋形( Smart Antenna beam-forming)

正方形ABCD的4个顶点各有1人.在某一时刻,4人同时出发以匀速v=10m/s按顺时针方向追逐下一人,如果他们始终保持对准目标,则最终按螺旋状曲线于中心点O.试求出这种情况下每个人的行进轨迹(Four vertices of square ABCD each one. At a time, 4 people starting at a uniform v = 10m/s in a clockwise direction chasing the next person, if they remain at the target, then press the spiral curve in the final Find the center point O. This road track of each person)

performance analysis of ieee 802.11b is done in this program. Analytical model used is based on the paper performance analysis of dcf by guisseppe bianchi

关于matlab作图的具体实现，详细介绍了matlab一维二维和三维作图的命令和实用方法！(Drawing on the concrete realization of matlab, matlab detailed one-dimensional two-dimensional and three-dimensional mapping of the commands and practical method!)

伪魏格勒分布源代码.适合于非稳态的时频联合分析,可直接用于MATLAB编程,无解压密码.(pseudo-source code distribution. Suited to the non-steady-state joint time-frequency analysis can be used directly in MATLAB programming, without extracting passwords.)

this code parsing xml tree by reading it and convert it to the matlab format, so we can use a xml document in matlab like an array or struct.

产生周期矩形信号的matlab源程序，希望对大家有帮助(Produce periodic rectangular signal matlab source, we want to help)

1. BPSK modulation of data which ever you input (default data is “MANIPAL REDDY”). 2. MANIPAL REDDY is changed into ASCII Format and into two-bit format for BPSK Modulation. 3. Chaos is used for spreading the binary bit sequence. 4. Uniformly distributed Noise is added to Spread signal. 5. After reception Chaotic Chip sequence is used to recover message . 6. Filter is used for removing spikes and noise. 7. Note the filter is used is just for showing a little realisitic picture. 8. Appropriate filter should be used. 9. The original data in binary and recovered data in binary format are compared
