As described in Sklar [1], the general analytical expression for M-FSK modulation is si(t)=√2ETcos(ωit+ϕ)0≤t≤Ti=1,...,M Eis the symbol energy. Tis the symbol time duration. ωiis the frequency term that ha
The elements of x must have values in the range of [0, M –1]. If x is a matrix, fskmod processes the columns independently. Example: randi([0 3],100,1) Data Types: double M— Modulation order integer power of two Modulation order, specified as an integer power of two. Example:...
Frequency Shift Keying (FSK) is a data communication most commonly used as a modulation mode. FSK method is simple, easy to implement, and demodulation not restore local carrier, ATM, Anti-noise and anti-fading strong performance. The drawback is a wide band occupation, the economy enough ban...
