Title: A preamble sequence for using synchronization of wireless communication system
Inventor: KIM JAE YEOL
IPC: H04L7/04
Filed: 2000-11-21
Abstract: PURPOSE: A device and a method for creating a preamble sequence in a wireless communication system are provided to create a preamble sequence for obtaining a synchronization of a transmission system, create a burst preamble sequence for catching a data start of a transmission system, and create a frame preamble sequence and a burst preamble sequence simultaneously. CONSTITUTION: In a method for creating an aperiodic recursive multiplex code by inputting a sequence having a predetermined length, two sequences are timely multiplexed by inputting the sequence having a predetermined length and a sequence multiplying the sequence by a sequence having repeated "+1" and "-1". When a sequence of a length decided through the multiplexing is created, the created sequence and a sequence multiplying the created sequence by a sequence having repeated "+1" and "-1" are outputted into the aperiodic recursive multiplex code. A multiplier(410) multiplies the sequence having a predetermined length by a sequence having repeated "+1" and "-1". Multiplexer(400) timely multiplexes the sequence having a predetermined length and the sequence from the multiplier(410). The output of the multiplexer(400) is re-inputted to the multiplier(410) and the multiplexer(400) until the aperiodic recursive multiplex code of a length decided from the multiplexer(400) is created.

CONSTITUTION: An inner shield(8) has a thin rectangular shape. The inner shield(8) includes a fixing portion fixed to a rail and an opening portion opened to an electron gun. A long side of the opening portion has a linear part(9), a main curve part(10), and a sub-curve part. The linear part(9) is formed on both ends of the long side. The main curve part(10) is formed on a center of the long side. The sub-curve part is used for connecting the linear part(9) with the main curve part(10). The linear part(9) is extended from both ends of the long side to the center of the long side. The main curve part(10) is formed from the center of the long side of the opening portion to an inside of the inner shield(8).
