Problems solved by technology

[0003] In the prior art, the relay device mainly uses two methods of DF (Decode-and-Forward, decoding and forwarding) and AF (Amplify-and-Forward, amplification and forwarding) to process the signal transmitted by the transmitting end device. However, the DF technology requires Decoding the signal passing through the relay device, and when the AF technology forwards the signal, it will carry channel noise and interfere with the communication effect
Both of the above methods will reduce the spectral efficiency of the signal

Abstract

The embodiment of the invention, which belongs to the field of the communication technology, provides a method and system for signal processing, and equipment. The method comprises the following steps that: according to a first reception constellation graph, a relay device demodulates a received signal emitted by an emission terminal device so as to obtain a first signal set; a second signal set is extracted from the first signal set and is mapped to a constellation point at a first forwarding constellation graph; and a corresponding forwarding signal is determined according to the constellation point and is sent to a receiving terminal device. According the embodiment of the invention, the method, the system and the equipment can be applied to signal processing.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to a signal processing method, device and system. Background technique [0002] In a wireless communication system, when the distance between the transmitting end device and the receiving end device is long, a relay device can be used between them. The relay device has the effect of enhancing the signal and improving the signal reception quality of the receiving end device. With the continuous development of the relay technology, the relay can not only be used to enhance the wireless signal, but also can be used to provide additional signal freedom and assist the receiving end device in signal processing. [0003] In the prior art, the relay device mainly uses two methods of DF (Decode-and-Forward, decoding and forwarding) and AF (Amplify-and-Forward, amplification and forwarding) to process the signal transmitted by the transmitting end device. However, the DF te...
