For the integrated system of underwater detection and communication, an emitted waveform
should satisfy both detection and communication requirements. The signal processing …

Testing the impropriety of complex signals is of great importance in complex signal
processing. Such test is often accomplished by the generalized likelihood ratio test (GLRT) …

In this work, a separating function estimation test (SFET) based detector is proposed for the
problem of impropriety test of complex signals. With the establishment of closed-form …

Gaussian minimum shift keying (GMSK) stands as a specialized form of continuous phase
modulation, offering inherent benefits such as a constant envelope and inherent coding …

The noise interferes with communication channels and fundamentally reduces the rate of
communication. Time-varying multipath fading makes reliable wireless transmission difficult …

In response to the problem of symbol to symbol crosstalk and high packet loss rate caused
by the lack of channel coding in ship automatic identification systems (AIS), a signal …

Nowadays, mobile communication is a part of our life and it is essential for us. On the
transmission and receiver side using quadrature amplitude modulation (QAM) with square …

Orthogonal frequency division multiplexing (OFDM) is a massive multicarrier technology
which has been widely applied for the huge amount of data transmission in wireless …

Существующие алгоритмы приема сигналов, не учитывающие эту интерференцию, не
обеспечивают высокой помехоустойчивости приема сообщений. В этих условиях …
