Understanding MSK, GMSK, FSK, GFSK Modulator and Demodulator with AWGN Channel Noise and BER

Understanding MSK, GMSK, FSK, GFSK Modulator and Demodulator with AWGN Channel Noise and BER
Scientech2809

Product Description

In today`s modern digital high-speed communication systems, the primary consideration is to achieve modulation with the power spectrum of acceptable bandwidth and constant amplitude of the modulated signal. Some of the most efficient modulation techniques are MSK and GMSK/GFSK. They are part of the Constant Phase Frequency Shift Keying (CPFSK) modulation family with a constant envelope. Since the modulated signal has constant amplitude, an efficient RF amplifier of class C can be used to minimize power consumption, an important consideration for battery- powered units.

TechBook Scientech 2809 is an ideal platform to study & experiments different topics like Minimum Shift Keying (MSK), Gaussian Minimum Shift Keying (GMSK), Frequency Shift Keying (FSK), Gaussian Frequency Shift Keying (GFSK) etc. which are the part of the Continuous Phase Frequency Shift Keying technique. TechBook 2809 also includes the study of AWGN noise & BER measurement. Built-in data acquisition system will help user to analyze the signals using real-time software.
