WebThe simplest CPFSK signal is obtained for the case in which the modulation index h = 2f d T is an integer. For this case, 4πf d nT is an integer multiple of 2π, and φ(n) = φ(n − 1) modulo 2π, regardless of whether the successive data symbols are the same or different. But phase angles that differ by integer multiples of 2π are the same for our purposes, so we can let … WebJun 9, 2016 · 1 - Yes I tried, BUT ! the only way I manage to make this works is by plugging the following blocks : File source -> RS encoder -> packed to unpacked -> CPFSK -> Quad demod -> binary slicer -> unpacked to packed -> RS Decoder -> File sink .
