Key 3G Technology COFDM: Related Implementation and Code Details

This document shares detailed information about program code implementations related to the 3G COFDM (Coded Orthogonal Frequency Division Multiplexing) technology, along with performance evaluation results. The codebase incorporates key algorithms including frequency domain equalization, cyclic prefix insertion, and QAM modulation/demodulation modules. Through rigorous testing, the implementation demonstrates robust performance in mitigating multipath interference and maintaining spectral efficiency. We encourage developers to download and experiment with the code, which includes comprehensive comments and configuration files for easy adaptation. The implementation follows standardized 3GPP specifications while optimizing computational efficiency through strategic memory management and parallel processing techniques. We believe this resource will provide valuable insights and practical assistance for wireless communication system development.
