The focus of this paper is to simulate a two channel optical WDM system for different bit rates. In this work, the comparison of both Binary and Duo binary modulation formats is carried out. Bit Error rate(BER) and Q factors are got improved with Duo binary modulation formats which will offer a significant performance benefits in digital systems.Keywords

The traditional Automatic Teller Machine (ATM) terminal customer recognition systems only rely on bank cards, passwords, and such identity verification methods which measures are not perfect and functions are too single. For solving the bugs of traditional ones, using a Biological Technology in new ATM terminal customer recognition systems (i.e.) fingerprint Mechanism. The chip of S3C2440 is used for the core of microprocessor in ARM9, furthermore, an improved enhancement algorithm of fingerprint image increase the security that customer use the ATM machine.Keywords

The multiple system loops refers to a two pair of particular radios on both side of the loop. But, multiple system loops wireless mesh networks occurred often link failures because of channel clashing, obstacles, and/or based on demand of bandwidth requirement. This cause major efficiency degradation in WMNs or more expensive manual network management. This paper deals about Autonomous Link Recovery System. This makes a Multi-radio WMN automatically recall its local network channel and radio. Autonomous Link Recovery System has been implemented on ns2 based simulation and improvement of 90% efficiency.Keywords
