System analysis of STBC-CDMA technique for secured image transmission using watermarking algorithm

摘要

Secured image transmission is an important task for image transmission through wireless medium. Proposed system is used to increase this image transmission. ACM encryption is used for encrypting the image. For more security, image is compressed using IWT. Code Division Multiple Access (CDMA) technique is considered to accommodate k number of users. Space Time Block Code (STBC) is a scheme for improving the reliability of data transmission and to increase diversity gain. With this system secured transmission of the image is enriched and bit-error-rate performance is also evaluated.
