Cell Initial Search - A Critical Process in GSM Systems with MATLAB Implementation

Cell initial search represents a critical procedure in GSM systems. This MATLAB program implements the cell search process to detect and decode the Broadcast Control Channel (BCCH). The input data, acquired through sampling, undergoes format conversion before processing. When BCCH is detected, the program outputs discovery information and performs demodulation/decoding operations. For BCCH-absent cases, error messages are generated. Includes detailed algorithmic documentation explaining implementation approaches.
