METHOD AND AN APPARATUS FOR GENERATING A SIGNAL WITH DIRECTIVITY AND A COMMUNICATION SYSTEM BETWEEN MULTIPLE USERS USING THE METHOD, CAPABLE OF GENERATING A SIGNAL WITH DIRECTIVITY DURING MULTILATERAL COMMUNICATION

摘要

PURPOSE: A method and an apparatus for generating a signal with directivity and a communication system between multiple users using the method are provided to divide sound sources received through one channel signal and position the divided sound sources, thereby respectively distinguishing the sound sources.;CONSTITUTION: A wireless communication unit receives signals with sound sources from at least one transmitter. A sub channel allocator(420) assigns each sub channel to the sound sources. A filter unit stores information about filter coefficients with different directivities. A channel adding unit(440) adds sound sources of the sub channels to generate one channel signal.;COPYRIGHT KIPO 2010
