Problems solved by technology

Because the in-band interference signal will pass through active components such as low noise amplifiers, if the in-band interference signal is strong enough, the in-band interference signal will cause nonlinear distortion in the active components
These distorted signals will enter the target signal frequency band and become noise, which reduces the performance of the multimode wireless receiver 10; moreover, it is difficult to design an ideal high-frequency band-pass filter, which causes confusion for engineers.

Embodiment Construction

[0047] The invention provides a signal receiving method and its device as well as a wireless broadband multi-mode receiving device, which are used to convert the interference signal into an anti-phase interference signal, and combine the broadband signal to obtain the target signal, eliminate the nonlinear distortion generated by the interference signal, and improve the The performance of the wireless wideband multimode receiver device.

[0048] Please refer to FIG. 3 , which shows a flowchart of a signal receiving method according to a preferred embodiment of the present invention. The signal receiving method is used for receiving a target signal, and the target signal exists in a wideband signal, wherein the wideband signal has a first bandwidth, and the target signal has a second bandwidth, and the first bandwidth is greater than the second bandwidth. In addition, the target signal has a center frequency in the broadband signal.

[0049]First, in step 302, a broadband sign...

Abstract

A signal receiving method is used to receive a target signal, wherein the target signal is stored in a wideband signal. And the method comprises that first, receiving a wideband signal, then removing the target signal from the wideband signal to obtain an interference signal, then converting the interference signal into phase-reverse interference signal, at least, combinging the wideband signal and the phase-reverse interference signal to obtain a target signal.

Description

technical field [0001] The present invention relates to a signal receiving method and its device as well as a wireless broadband multi-mode receiving device, and in particular to a high-efficiency signal receiving method and its device as well as a wireless broadband multi-mode receiving device. Background technique [0002] Modern wireless communication technology develops at an extremely fast speed, from a single analog communication system that can only carry basic audio signals and text information in the early days to today's increasingly complex digital communication system that transmits a large amount of multimedia information. In addition, diverse communication protocols are also established to meet diverse communication requirements. Nowadays, popular communication protocols such as PHS, GSM, GPRS, WCDMA, CDMA2000 or WLAN have been used all over the world. However, most regions use different communication protocols, so people cannot travel around the world and use...
