Different coherent detection methods for carrier acquisition and channel decoding

The method of carrier acquisition which we have used in this paper is a modified form of binary search algorithm. This modified search algorithm is a hybrid of two search algorithms which are "Binary search tree" and "Modified search tree". Firstly the modulated signal is received by the receiver where it is analyzed to acquire carrier. The receiver consists of two sections. One section uses the binary search tree process while the other section uses the modified search tree. Firstly binary search tree is used for carrier acquisition method and secondly the modified search tree is used. The overall tree diagram is a real-time tree diagram and it is formed during the process of carrier acquisition. This hybrid tree structure proves more helpful for carrier acquisition process as it is more accurate, low cost, less complex and less time consuming.
