Minimum shift keying: A spectrally efficient modulation
TL;DR: The main attributes of MSK, such as constant envelope, spectral efficiency, error rate performance of binary PSK, and self-synchronizing capability will all be explained on the basis of the modulation format.
Journal ArticleDOI
Continuous phase modulation
TL;DR: A number of methods for constructing constant amplitude signals which significantly outperform MSK are considered, and at what level of complexity these improvements are obtained and realized.

MSK and OK-QPSK signal demodulator
TL;DR: An MSK or OK-QPSK data signal demodulator includes a filter and limiter for filtering and amplitude limiting the data signal, a timer for generating a timing signal indicating elapsed time, and a microcomputer coupled to the limited data signal from the limiter and the timing signal from a timer as discussed by the authors.
Patent
Maximum distance from zero crossing MSK demodulator
TL;DR: In this article, a maximum distance from zero-crossing demodulation method for MSK or OK-QPSK signals is disclosed which utilizes the zero crossing information for establishing a bit edge reference and an optimum sampling point situated essentially midway between the zerocrossings of the higher of the two incoming signalling tones.

Spectrum extension research of Radar-communication integrated waveform
TL;DR: This paper will elaborate from the following aspects: Mathematical expression of the integrated waveform in order to deduce the reason of spectrum extension and propose solutions accordingly, and the practicability of the method proposed by in this paper by implementing integrated wave form and algorithm on FPGA using VHDL language.
