Linear Feedback shift Registers (LFSRs) are widely used in encoders like Cyclic Redundancy Check (CRC) for generating error detecting codes. In order to achieve high speed communication, parallel processing is performed in the serial CRC. Since this method increases the circuit complexity, the speed gets limited. State space transformation is a method that can be used to reduce the circuit complexity. Therefore, an efficient transformation matrix is needed in this method. In this paper, a method to construct a transformation matrix and an approximatesearching algorithm to generate certain vectors, which are used in transformation matrix are implemented.
