Random pulse generator based on FPGA (field programmable gate array)

Abstract

The invention claims to protect a random pulse generator based on an FPGA (field programmable gate array). The random pulse generator mainly comprises a general asynchronous receiving and sending transmitter module, a control and command analysis unit, a pseudo-random number generator module, a judging module, a weighing factor module and a gaussian white noise generator module, wherein the general asynchronous receiving and sending transmitter module is used for receiving control information from a host and then sending the control information to the control and command analysis unit for command analysis; the control and command analysis unit is used for resetting a system, setting inside parameters and analyzing the command; the pseudorandom number generator module is used for generating the pseudorandom number sequence; the judging module is used for judging the threshold value obtained by the control and command analysis module and the value generated by the pseudorandom number module and outputting 0 and 1 pulse sequences; the weighing factor module is used for generating the weighing factors; the gaussian white noise generator module is used for generating gaussian white noise. The random pulse generator has the advantages that the structure is simple; the realization is easy; the integration degree is high; the hardware consumption is low; the generator parameter is flexible and settable.

Description

Technical field [0001] The invention relates to a random pulse generating device, which belongs to the field of digital information processing. Specifically, it is a device that generates random impulse noise based on FPGA. Background technique [0002] In recent years, PLC has developed rapidly and its transmission rate has been greatly increased. It is called Broadbandover Power Line (BPL) and has become a new access technology to solve the bottleneck of broadband networks-the "last mile". Under the background of energy informatization, a series of concepts such as smart grid, Internet of Things, and energy Internet have been put forward, making PLC a new development direction in energy measurement and control. For example, technologies such as Automated Meter Reading (AMR) and Automated Meter Management (AMM) have been promoted in some regions. [0003] The noise in broadband power line communication is far more complicated than the noise in other dedicated communication lines...
