CDMA业务信道卷积编码实现，根据上下行信道区分生成不同码率的卷积码序列，original_sequence是原始输入序列，channel_select是信道选择参数，其中下行码率为1/2，上行信道为1/3 (CDMA business channel convolutional coding to achieve, according to the distinction between upper and lower line to generate a different channel bit rate of the convolutional code sequence, original_sequence is the original input sequence, channel_select is channel selection parameters, which downlink bit rate of 1/2, upstream channel for the 1/3)

说明：  基于MATLAB的Harris特征点的检测(harris feacture points detector)

离散系统滑模跟踪的kalman应用，希望对大家有用(Sliding mode discrete-time systems kalman tracking applications, in the hope that useful to everybody)

converter is suppressed according to CISPR 22 standard limits. The fundamental frequency component with higher order harmonics of 2 MHz resonant converter after the application of filter is at 33.18 dBµ V. The designed filter has attenuated the common mode conducted noise by 140 dBµ V.

说明：  discrete continuous transform used in mobile communication, perfectly analyzed.
