Problems solved by technology
[0004] However, the receiving section and the transmitting section of wireless energy-carrying communication have added energy transceivers. The system channel information obtained in the current MIMO system only considers the information transmission process between user nodes, and does not consider the energy transmission. Therefore , there is a certain error between the system channel information obtained by the transceiver and the real channel information, which reduces the communication quality of the system

Embodiment Construction
[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0031] A communication system generally consists of a base station, a relay, and a user node. To realize point-to-point communication between user nodes, the user node needs to uplink the signal to the relay or base station, and then downlink the signal to the receiver at the opposite end by the relay or base station. , the link uplinking the user...

The invention provides an obtaining method and apparatus for a simultaneous information and power transfer (SWIPT) type transceiver model. The method comprises: according to a minimum mean square error and a channel capacity of an information decoding module receiving signal of a user node, an objective function of a SWIPT type transceiver model is obtained; a transmitting power of a base station is obtained based on a transmitting signal of the base station; according to a signal sent by the base station to an energy receiving module, a receiving signal of the user node is obtained; and on the basis of the objective function, the transmitting power of the base station, and the receiving signal of the user node, a first system model of the SWIPT type transceiver is obtained. According to the provided method and apparatus, the base station and user transceiver model of the SWIPT system are obtained and optimized, thereby improving the communication quality of the SWIPT system.
Description
technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for obtaining a model of a wireless portable energy communication transceiver. Background technique [0002] With the rapid development of wireless communication technology, the equipment in the wireless communication network consumes more and more energy. Since Simultaneous Information and Power Transfer (SWIPT) uses the same wireless carrier to transmit information and energy simultaneously Under the limited energy, nodes such as base stations not only transmit information for nodes within the coverage area, but also charge microwave energy for user nodes, so that mobile terminals can reduce their dependence on battery capacity and achieve efficient and reliable communication. Therefore, wireless Portable energy communication has been widely used. [0003] At present, the main research scenarios of wireless energy-carrying communication are i...
