Description

Communication receiver architecture and communication receiving method for separation detection joint judgment
Technical Field
The invention relates to the fields of signal detection, wireless communication and the like, in particular to a communication receiver architecture for separating detection and joint judgment and a communication receiving method.
Background
In recent years, wireless communication technology has been remarkably developed in various fields, and the fifth generation and future mobile communication have higher requirements on communication technology and can be used for realizing large-scale internet of things. The medical internet of things is an important research direction of the future internet of things, and in the aspect of human body wireless communication, ultrasonic waves conforming to medical safety power cannot generate side effects on a human body, so that the medical internet of things can be used as a reliable medium of the future medical internet of things.
In research in various fields of communication technology, a sending end scheme is gaining wide attention, for example, for radio frequency wave wireless communication, a plurality of classical sending schemes have been proposed to improve performance of a communication system, such as spread spectrum modulation, ultra wideband technology, Multiple Input Multiple Output (MIMO) technology, and the like. For human body wireless communication, technologies such as ultrasonic broadband and high-order modulation can be applied to a transmitting end to improve the communication rate and resist communication interference. And the scheme of the receiving end is less researched, and two traditional receivers, namely a coherent receiver and a noncoherent receiver, are generally adopted. Conventional coherent receivers utilize partial degrees of freedom of the channel, also referred to as the dimensionality of the signal space of the received signal, such as the amplitude, phase, frequency, position, etc., of the received signal for signal reception; conventional non-coherent receivers exploit the freedom of the other part of the channel, i.e. the power and energy of the signal for signal reception. Because the two traditional receivers only utilize partial freedom degrees of channels and do not utilize all the freedom degrees of the channels, the communication error rate is higher.
In recent years, a signal coherent receiver and an energy receiver are adopted by a receiver to perform wireless communication and wireless energy transmission respectively, so that a certain hardware basis is provided for simultaneously using the coherent receiver and the non-coherent receiver to perform signal reception. However, wireless energy transmission and wireless communication require two separate circuits for energy storage and communication, respectively, which undoubtedly increases the hardware complexity of the communication receiver.
