Title: Method for preventing collision between packet data calls in high speed wireless packet data system
Inventor: KIM EUN HYE
IPC: H04L12/56
Filed: 2000-12-23
Abstract: PURPOSE: A method for preventing a collision of packet data calls in a high-speed wireless packet data system is provided to prevent a call collision generated when a plurality of terminals attempt packet call access. CONSTITUTION: A terminal initializes a random number and a call access time(ST21). Then the terminal transmits preamble data to a base station at the call access time(ST22) and judges whether synchronous acquisition is achieved(ST23). If synchronous acquisition is made, the terminal transmits packet data(ST24). A PDMU board in the base station executes an error check for the received packet data(ST25). In case that no error is detected from the received packet data, the PDMU board increases the random number sequentially(ST26). In case that a new random number is set, the PDMU board adds the new random number to a signaling channel and executes data transmission to the terminal(ST27). If the new random number is received, the terminal determines a call access time suitable for the received random number and executes the transmission of preamble data according to the determined call access time(ST28).

Title: ECHO Canceller of the ADSL system and controlling method therefor
Inventor: SONG IN CHEOL
IPC: H04B3/20
Filed: 2000-12-29
Abstract: PURPOSE: An echo cancel apparatus in ADSL(Asymmetric Digital Subscriber Line) system is provided to check the mismatched degree between a symbol constructed by a constant frame data and a symbol of an echo frame and perform a linear convolution about the distortion of both ends of the echo frame, thereby minimizing a lowering of capability. CONSTITUTION: A modulator(1) modulates a communication signal inputted through a transmission line through the ADSL method. A block delay(2) delays only one frame among the modulated signals and then outputs the delayed signal. A first adder(3) checks a frame signal from the modulator(1), adds the delayed frame signal inputted from the block delay(2) to the frame signal and then outputs the added signal. An echo canceller(4) outputs an echo pass signal among the communication signals to a frequency domain and updates a tap signal according to an echo miss included to the echo signal and then outputs the tap signal. A signal conversion unit(5) converts the signal of the echo canceller(4) of the frequency domain into a signal of a time domain and then outputs the converted signal to an echo pass impulse response signal. An echo correction block(6) calculates the echo frame signal inputted from the first adder(3) in order to correct the distorted part within the range of the echo pass impulse response signal inputted from the signal conversion unit(5) on the basis of a border point of the next echo frame signal at a minimum. When the mismatched sample by the echo correction block(6) is above 1/2 of the entire length of the data frame signal, a mismatch information production unit(7) checks the state and outputs the checked signal.
