| Outline of Final Research Achievements |
We studied on time synchronization, an important issue in wireless sensor networks, using a novel communication architecture called analog CDMA. By modulating analog waves using CDMA, a sink node can collect continuous analog sensor data from multiple points. According to our evaluation, the analog CDMA communication can achieve SNR of 20dB, which menas the communication architecture can be applied to acceleration sensors whose noise level is several 100 ug/sqrt(Hz).
