a perimater time ca for quen bee problem

matlab 一些经典算法，包括数值拟合，回归，插值、解方程等(matlab some classic algorithms, including numerical fitting, regression, interpolation, solving equations, etc.)

The implementation was built on Matlab/Simulink using fundamental components in Simulink to demonstrate how reliably complex modulation schemes can be built, cost effectively and efficiently [5]. The design of ZigBee transmitter using MSK modulation is shown in the Figure 1. Here we map input data bits to 8-chip PN sequences to be transmitted and results in a chip rate of two mega chips per second. After that, resultant chip sequence is send to the serial to parallel converter. It is used here to separate the odd and even bit indexed chips. Following this bipolar data formatting is performed and signal modulated with a 2.4 GHz carrier on the In Phase and QuadraturePhase data stream and adds it to get the required transmitter output signal.
