Embodiment Construction

[0020] Certain terms are used in the description and claims to refer to particular elements. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. "Includes" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". In addition, the term "coupled" herein includes any direct and indirect means of electrical connection. Therefore, if it is described herein that a first device is coupled to a second device, it means that the first device may be directly electrically connected to the second device, or indirectly electrically connected to the second device through other devices or connection means.

Abstract

The invention provides a signal receiving device, a signal receiving method and a global mobile communication system telephone, wherein, the signal receiving device includes a receiver, and the receiver selects a combined detection Viterbi demodulator or a second Viterbi demodulator based on at least one characteristic of the received signal, thereby demodulating the received signal. The combineddetection Viterbi demodulator combinedly demodulates a required signal component of the received signal and an interfering signal component; and the second Viterbi demodulator demodulates the requiredsignal component without demodulation of the interfering signal component. The signal receiving device, the signal receiving method and the global mobile communication system telephone can acquire better receiving signal quality and reduce disturbance.

Description

technical field [0001] The present invention relates to a receiver architecture, and in particular to a signal receiving device, a signal receiving method and a GSM phone. Background technique [0002] When multiple mobile phones (cell phones) are used in the network at the same time, signals related to different mobile phones may interfere with each other, resulting in signal quality degradation or even dropped calls. In some cases, the Joint Detection Viterbi (JDV) algorithm can be used to jointly demodulate (or decode) the desired signal and the interference signal, so as to obtain better received signal quality and reduce interference. Contents of the invention [0003] In order to obtain better received signal quality and reduce interference, the following technical solutions are provided: [0004] An embodiment of the present invention provides a signal receiving device, including a receiver, the receiver adaptively selects a joint detection Viterbi demodulator or a...
