A wireless sensor node processor with digital baseband based on adaptive threshold adjustment for emotional lighting system

Abstract

In this paper, we present a wireless sensor node processor for emotional lighting system. Proposed wireless sensor node processor consists of an 8-bit embedded microcontroller, media access control (MAC) accelerator and digital baseband based on adaptive threshold adjustment (ATA) for enhancing the pseudo noise (PN) code acquisition. We fabricate a wireless sensor node processor using 0.18 mum CMOS technology and organize wireless sensor network for emotional lighting system. These results show it can be successfully applied in wireless sensor networks for further emotional consumer applications
