“…It can automatically identify the source of the signal and then directly implement the modulation of MPSK signals. The design implements the function of integration, and reduces cost [12,13]. The premise of achieving the identification algorithm of time and frequency overlap signals in singlechannel is that we can estimate in advance the carrier and bit rate of dual signal.…”

MPSK is a modulation method which uses various phase states of the carrier to describe digital information. And it is widely used in the field of digital communications. Now, the applicable scope of MPSK signal modulation is too narrow, and it is necessary to know the type of signal source to modulate in advance, which have limit the development of MPSK. In this paper, we use the identification algorithm of time and frequency overlap signals in single-channel to differentiate and modulate the type of MPSK signals. This design improves the applicability and operability of the modulator. At the end of this paper, we merge all the modules to implement the MPSK signal modulator with the function of signal sort recognition. This design uses the hardware description language VHDL to program, Quartus II 8.0 to integrate andwire, and ModelSim platform to simulate. Besides, MPSK modulator based on FPGA has a good practical application.

“…Distributed processing deals with extraction of information from the local data received and processed by each sensor nodes that are randomly distributed at diverse locations [1] [2]. The applications of distributed processing are measurement of temperature, humidity, pressure, wind direction and speed, illumination intensity, vibration intensity, sound intensity, power-line voltage, chemical concentrations, pollutant levels, monitoring a moving target in a region monitored by a collection of sensors deployed in the field and so on [3] [4].…”

Adaptive algorithms are applied to distributed networks to endow the network with adaptation capabilities. Incremental Strategy is the simplest mode of cooperation as it needs less amount of communication between the nodes. The adaptive incremental strategy which is developed for distributed networks using LMS algorithm, suffers from drift problem, where the parameter estimate will go unbounded in non ideal or practical implementations. Drift problem or divergence of the parameter estimate occurs due to continuous accumulation of quantization errors, finite precision errors and insufficient spectral excitation or ill conditioning of input sequence. They result in overflow and near singular auto correlation matrix, which provokes slow escape of parameter estimate to go unbound. The proposed method uses the Leaky LMS algorithm, which introduces a leakage factor in the update equation, and so prevents the weights to go unbounded by leaking energy out.
