该程序是一个振荡相位噪声模型。相位噪声是衡量频率标准源(高稳晶振、原子频标等)频稳质量的重要指标，随着频标源性能的不断改善，相应噪声量值越来越小，因而对相位噪声谱的测量要求也越来越高。(The program is a model of phase noise oscillator. Phase noise is a measure of frequency standard source (high stability crystal oscillator, atomic frequency standard, etc.) an important indicator of the quality of the frequency stability, with the frequency standard source performance continues to improve, the corresponding noise value smaller, and thus the phase noise spectrum of the measurement requirements higher and higher.)

This folder contains several codes for energy detection and match filter.

两自由度非线性比例前馈四轮转向模型，测汽车质心侧偏角和横摆角速度(Two degrees of freedom nonlinear feedforward four-wheel steering model, auto measuring centroid side-slip Angle and yawing angular velocity )

Simulink® and Stateflow® model of a full duplex Bluetooth communication link transmitting HV1, HV2, HV3, and SCORT [1] voice packets, and DM1 data packets. A system parameters block configures the whole model s packet type, slot pair and channel type. Stateflow is used to implement the acknowledgement scheme for the data packets and the SCORT receiver state machine. NOTE: A version of this model which works with the current release of MATLAB and Simulink is shipped with the Communications Blockset™ . The model includes wave file I/O, CVSD speech coding, HEC, payload CRC for DM1, FEC, framing, GFSK Modulation, frequency hopping, hop sequence generation, an 802.11b interferer, BER meters, throughput meters, plus spectrum, timing and spectrogram plot (which can be turned-off).
