Problems solved by technology

[0005] However, the communication device may receive noise due to electromagnetic coupling of the antenna or electromagnetic interference (EMD), or cause noise due to the operation of an analog circuit
This noise can cause digital processing failures in communication modems

Embodiment Construction

[0019] Exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings.

[0020] figure 1 is a block diagram illustrating an apparatus for recognizing a communication signal in a preceding stage of a communication modem according to an example embodiment.

[0021] refer to figure 1 , the device 100a for identifying communication signals in the preceding stage of the communication modem 200 may include a port 110a and a communication signal identifying unit 120a.

[0022] Port 110a may receive communication signals. For example, the port 110a may have a structure of an electrical connection structure (e.g., a pin, a pad, a solder ball, a land, etc.), which may be electrically connected to an RF IC or a baseband IC, may have an output impedance similar to that of the baseband IC. Corresponding input impedance, and may have a combination or logic circuit structure of multiple switches to sequentially receive digital c...

Abstract

The invention provides an apparatus and a method for identifying a communications signal in a preceding stage for a communications modem. The apparatus includes a communications signal identifying unit configured to receive a communications signal through a port, deliver data included in the communications signal to a communications modem, and sample the communications signal which has passed through the port during every unit length to detect a unit length pattern corresponding to a start of communication and a unit length pattern corresponding to an end of communication. When a length from the start of communication to the end of communication is equal to or smaller than a reference length, the communications signal identifying unit delivers a data process stopping signal to the communications modem such that the communications modem stops a data reading operation.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to Korean Patent Application No. 10-2017-0177148 filed in the Korean Intellectual Property Office on December 21, 2017, the disclosure of which is incorporated herein by reference in its entirety. technical field [0003] The present disclosure relates to an apparatus and method for identifying a communication signal in a preceding stage of a communication modem. Background technique [0004] Generally, a communication device may receive a radio frequency (RF) signal through an antenna, perform analog processing (eg, amplification, filtering, frequency conversion, analog-to-digital conversion, etc.) on the received RF signal, and send the processed signal to a communication modem. The communications modem can digitally process the received signal to obtain the information included in the RF signal. [0005] However, the communication device may receive noise due to electromagnetic coup...
