Title: The full duplex noise and echo elimainating method for handsfree
Inventor: SEO GWANG IL
IPC: H04B1/38
Filed: 2000-08-12
Abstract: PURPOSE: A method for removing a noise and an echo of a hansfree with a full dual type is provided to remove the GSM noise and echo sound generated in the hansfree of a GSM cellular phone by calculating an output microphone signal in a state in which a speaker is closed and opened and outputting a normal output microphone signal with reference to a peripheral noise. CONSTITUTION: Variables of a voice signal of a user through an encoder and a decoder are initialized by a digital signal process unit, and an interrupt is turned on for performing a noise removing mode(24-26). A sample value of a voice signal transmitted through a microphone is collected, and a sample value of a voice signal outputted to a speaker(27,28). If the sample value of the speaker is more than the sample value of the microphone, the speaker is closed for measuring a noise. A closed time of the speaker is calculated for turning on a flag of an adaptive filter(32,33). If the sample value of the speaker is less than the sample value of the microphone, the speaker signal and the microphone signal are continuously collected in a state in which the speaker is opened(34,36). A ratio of the collected speaker signal and microphone signal is calculated, and an adaptive time of the adaptive filter is set(37). An adaptive filter LMS(Least Mean Square) algorithm is performed, and an echo value is obtained by a value(speaker signal * adaptive filter coefficient) and an output microphone signal is calculated by a value(microphone signal-echo value)(39,40). A normal output microphone signal is outputted by a value(output microphone signal-peripheral noise)(41).

The CPU loads an initial software from a ROM and outputs a corresponding initialization signal to every block of a system(S2). The CPU determines whether data transmitted and received through an internal data bus and a block is an ATM signal processing or an E1 signal processing(S3). If the data is E1 signal processing, an E1 line interface transformer outputs the E1 data inputted from an E1 framer/transceiver to the ATM interface unit(S4). The ATM interface unit receives the E1 data and converts it to an output ATM rate(S5). The ATM interface unit converts the E1 data into an ATM frame structure and performs an ATM data communication through an interface of a coaxial cable or an optical cable(S6). If the data is an ATM signal processing(S3), it is determined whether it is an input through an IPC or an input through the E1 interface(S7). If the data is an input through the E1 interface, the E1 framer/transceiver outputs the E1 data to a parallel bus controller through the internal data bus(S8). The parallel bus controller converts the E1 data in an ATM data form and outputs it to the ATM interface unit(S9).
