In digital modulation, minimum-shift keying (MSK) is a type of continuous-phase frequency-shift keying that was developed in the late 1950s by Collins Radio employees Melvin L. Doelz and Earl T. Heald. [1]

Apr 14, 2010 · Compare Performance and spectral efficiency of bandwidth-efficient digital modulation techniques (BPSK,QPSK and QAM) on their theoretical BER over AWGN.

Dec 10, 2019 · Bit Error Rate (BER) simulation was carried out in MATLAB using one sample per symbol. This is done to keep the processing time to a minimum, however, the reader is encouraged to experiment with multiple samples per symbol. The environment under which the MSK BER is calculated is AWGN.

Gaussian Minimum Shift Keying (GMSK) is a modification of MSK (i.e. CPFSK with h = 1/2). A filter used to reduce the bandwidth of a baseband pulse train prior to modulation is called a pre-modulation filter. The Gaussian pre-modulation filter smooths the phase trajectory of the MSK signal thus limiting the instantaneous frequency variations.

Minimum shift keying (MSK) is specific case of continuous phase frequency shift keying (CPFSK) where the peak frequency deviation is one half the bit rate. The characteristics of MSK include constant envelope, spectrally efficient suppression of …

The light-emitting diode (LED) model in short-range VLC is introduced, the bit error rate (BER) performance of MSK is compared with GMSK by Monte Carlo simulations and experiments. The results are shown and MSK has the better BER performance than GMSK is verified.

Bit error rate (BER) for uncoded data over an AWGN channel, returned as a scalar or vector. The BER is computed for each E b /N 0 setting specified by input EbNo according to the modulation type specified by input modtype and related dependencies.

Jun 15, 2009 · In this post, we will discuss MSK transmission as a variant of offset-QPSK technique. Further, we will discuss the receiver structure and show that bit error rate with coherent demodulation of MSK (using time) is equivalent to that of BPSK modulation. The channel assumed is AWGN.

In order to introduce MSK into satellite laser communication, the bit-error rate (BER) performance of the MSK scheme is investigated in uplink communications under the influence of atmospheric turbulence consisting of weak fluctuation and beam wander.

Gaussian Minimum Shift keying is used in GSM (Global system Mobile communication). It is also used in Cellular Digital Packet Data (CDPD), Digital European Cordless Telephone (DECT). GMSK supports better spectral efficiency the use of this is to have less sidebands as par with other technologies.
