Design, Analysis, Simulation and Implementation of 3D Polar FSK Modulator
2019
The requirements for Wireless Personal Area Network are less band-width, high speed, low probability of error and reduced multipath interference. In M-ary Phase Shift Keying, M-ary Amplitude Shift Keying and M-ary Quadrature Amplitude Shift Keying, as N increases, the probability of error increases, even though bandwidth decreases. In M-ary Frequency shift keying as N increases, the probability of error decreases but bandwidth increases. In general, while working with the wireless systems using these techniques, various problems encountered are: multi-path fading, single carrier fading, time dispersion which leads to inter symbol interference, lower bit rate capacity, less power efficiency and less spectral efficiency. Hence there is a need to design a new modulation technique which fulfills all the requirements of Wireless Personal Area Network. We have implemented a spectrally and power efficient modulator of 3-Dimensional Polar Frequency Shift Keying modulation.
