Abstract: PURPOSE: A PART reduction technique for a maritime communication OFDM is provided to reduce complexity while showing similar performance compared to the existing technique using a CCDS technique. CONSTITUTION: A PART reduction technique for a maritime communication OFDM includes a stage of generating a plurality of candidate signals by performing an additional complex addition for combining an IFFT in an OFDM signal and a stage of generating a signal by differently assigning a circulation delay time of one circulation delay signal combined with each candidate signal.

Abstract: A debugging method for wireless sensor networks considering mobile sink nodes is disclosed. This method comprises a step of collecting value index to determine the cause of a bug from a sensor node and a sink node; a step of detecting the bug using the value index collected; a step of drawing the basic cause of the bug; and a step of showing the basic cause to a user.
