WebThe comm.GMSKDemodulator System object™ uses a Viterbi algorithm to demodulate a signal that was modulated using the Gaussian minimum shift keying (GMSK) method. … WebIn GSM, transmissions consist of TDMA frames. Each GSM TDMA frame consists of eight time slots. The transmission data content of a time slot is called a burst.As described in Section 5.2 of 3GPP TS 45.011, a GSM time slot has a 156.25-symbol duration when using the normal symbol period, which is a time interval of 15/26 ms or about 576.9 …
