Title: Apparatus and method for transmitting preamble of access channel
Inventor: KIM YEONG GI
IPC: H04B1/707
Filed: 1998-08-17
Abstract: PURPOSE: Apparatus and method for transmitting a preamble of an access channel in multiple access mobile telecommunication system is provided to guarantee the same preamble detection and simultaneously minimize an interference degree of the reverse directional link. CONSTITUTION: The apparatus comprises a preamble generating unit(320). The preamble generating unit comprises a transmission controller(326) and a switching element which make it possible to perform a discrete preamble transmission within a preamble region.
