Patent ID: 7836114

Claim:
An apparatus for generating a ranging binary code sequence at a high-speed, comprising: an initial register value generating means for generating an initial register value of each of only valid ranging codes in a predetermined range based on an initial value; a storing means for storing the generated initial register values of the only a minimum ranging codes; a binary code sequence generating means for generating a binary code sequence of a corresponding ranging code based on the stored initial register value of given ranging code; and a control means for receiving a first frame including a first uplink permbase value, which is a UL_PermBase value, and a first ranging code from a base station, recording the first uplink permbase value in the register of the initial register value generating means, generating the initial register value of each of ranging codes ranging from the ranging code 0 to the received first ranging code number_through the recorded initial register value, controlling the above initial register value storing procedure, reading an initial register value of a corresponding ranging code number in the storing means, and controlling each constitutional element to generate a binary code sequence.
