Performance Analysis of Super Dense Multiple Access(SDMA) Communications Systems Using Almost Periodic Function Codes
Tomoya Naohara, Ken Umeno (Kyoto Univ.) NLP2014-101
Abstract (in Japanese) (See Japanese page) 
(in English) We propose a new communications system that is different from what is using PN codes or chaotic codes. It is based on the Almost Periodic Function. Although It is becoming clear that these new Almost Periodic Function Codes can dramatically improve the Synchronous Communications Systems, it is unknown that these codes improve the Asynchronous Systems. Therefore, we show that these codes can materially improve the Asynchronous Systems by using the computer simulations. Also, we describe that systems performance can depend on how to assign prime numbers used in the Almost Periodic Function Codes to each user.
