Embodiment Construction

[0030] A specific embodiment according to the present invention is a communication system, and its functional block diagram is shown in figure 2 . It should be noted that the term “invention” here is used to refer to the inventive concept presented in these embodiments, but its scope is not limited to the embodiments themselves. In addition, the mathematical expressions in the present invention are used to illustrate the principles and logics related to the embodiments of the present invention, and do not limit the scope of the present invention unless otherwise specified.

[0031] The communication system 200 includes a sample rate converter 210 and a controller 215 which can be changed in configuration. In this embodiment, the sampling rate converter 210 is included in the digital circuit 220 to convert the input sampling rate F IN A digital signal is converted to another output sampling rate F OUT converted signal. The converted signal is then sequentially provided to ...

Abstract

The present invention provides a communication system, which comprises a sample rate converter enabling to change the configuration, and a controller. The sample rate converter is used for converting a digital signal with a first sample rate to a converted signal with a second conversion rate. The sample rate converter is operated under a first configuration or a second configuration different from the first configuration. The controller enables dynamic control of the sample rate converter to be operated under either the first configuration or the second configuration according to at least a limited condition.

Description

technical field [0001] The present invention relates to sample rate converters (SRCs), and more particularly to sample rate converters that can adapt to changing operating configurations. Background technique [0002] With the advancement of electronic-related technologies, various types of communication devices are becoming more and more popular. Most of the transmitters or receivers in current communication equipment include a front-end analog circuit and a back-end digital circuit; a digital-to-analog converter or an analog-to-digital converter is provided between the two circuits with different signal types. [0003] figure 1 A simplified functional block diagram of a transmission circuit in a 3rd Generation Partnership Project (3GPP) communication device is presented. In order to prevent the high-order harmonics of the pulses in the digital signal from interfering with the analog circuit, the digital circuit 120 and the analog circuit 160 generally need to be physical...
