What is advantage of MSK over QPSK?
Overall, for direct detection systems, MSK has an advantage over QPSK because the compensation of nonlinearities on the receiver side is not possible and MSK performs better under these circumstances [2]. Furthermore the receiver for MSK is easier to implement. For coherent detection, this advantage is reduced.
How do you demodulate MSK?
Description. z = mskdemod(y,nsamp) demodulates the complex envelope y of a signal using the differentially encoded minimum shift keying (MSK) method. nsamp denotes the number of samples per symbol and must be a positive integer. The initial phase of the demodulator is 0.
