![]() BPSK vs QPSK -Difference Between BPSK and QPSK modulation techniques. 8PSK 8-PSK modulation or multilevel PSK or phase shift keying modulation technique. MSK-GMSK MSK modulation,GMSK modulation and GMSK demodulation. QAM-This page describes QAM modulation technique with equation and constellation diagram. QPSK -This page describes QPSK modulation technique with equation and constellation diagram. ➨ PSK modulation python code Modulation typesĪM vs FM vs PM AM FM PM MATLAB Code What is modulation BPSK-This page describes BPSK modulation technique with equation and constellation diagram. Python simulation codes for ASK, FSK and PSK modulation types In MFSK (Multiple FSK), more than one bits are represented byĪlso refer advantages and disadvantages of Than two frequencies have been developed. In order to overcome drawbacks of BFSK, multiple FSK modulation techniques with more ➨The BER (Bit Error Rate) performance in AWGN channel is worse compare to PSK modulation. ➨It uses larger bandwidth compare to other modulation techniques such as ASK and PSK. ➨FSK transmitter and FSK receiver implementations are simple for Hence it is robust against variation in attenuation through if you digitize your voice with Analog to digital convertor then your voice will change to some 0 and 1. ➨It has higher immunity to noise due to constant envelope. For Complete understanding you should read system communication book, but i get an example : your voice is wave. ➨It provides high SNR (Signal to Noise Ratio). Benefits or advantages of FSKįollowing are the benefits or advantages of FSK: It is also used in coaxial cable based LAN (Local Area Network) at higher frequencies.It is used for high frequency radio transmission from 3 to 30 MHz.It is used on voice grade lines for data rates upto 1200 bps. ![]() Refer difference between ASK vs FSK vs PSK >.įollowing are the typical applications of FSK modulation. In this equation, f2 and f2 are offset from carrier frequency (Fc) by equal but opposite Here amplitude and phase of theĬarrier remain constant while carrier frequency is changed.īinary FSK (BFSK) can be represented by following mathematical equation: The FSK modulation technique uses two different carrier frequencies toĪs shown in the figure-1, carrier frequency f1 represents binary data one andĬarrier frequency f2 represents binary data zero. It is a digital modulation technique which shifts the frequency of theĬarrier with respect to binary data signal. It mentions FSK advantages or benefits and FSK disadvantages or drawbacks. This page covers advantages and disadvantages of FSK. FSK Advantages | FSK Disadvantages | Frequency Shift Keying
