The marine application using a wireless system is demanded for the environmental monitoring or the security. We executed a research project of "Marine ubiquitous sensor network especially at harbor and shore area" which put "contribution to industrial activation of harbor area" that utilized GNSS based on these back-grounds in mind. Then, We measured the receiving rate and the receiving sensitivity when adding the white noise and colored noise in the closed communication channel using the commercial DSSS-wireless module. The transmission signal buried in the white noise of the high-level was decoded. As the result of this report, the difference of the processing gain was close to the theoretical value, and the maximum receiving sensitivity of this module was -125.5dBm.
