| description | In this paper blind equalization algorithms based on digital
watermarking are presented. Training sequence is sent along with the data in
the form of watermark. Robust CDMA based watermarking algorithm is used to
watermark the data. Watermark, which is spread over the data, does not
consume extra bandwidth. So with the help of extracted watermark channel can
be equalized just by using simple mean square algorithm. Two algorithms for
equalization are proposed in this paper. In algorithm I the receiver does not
require to know training sequence in advance. Using algorithm II, the sender
does not require to send training sequence either, and data can still be
equalized using simple LMS algorithm at low computational complexity. |
