Resource Overview
Modified source code from Wang Yumin's "Key OFDM Technologies and Applications" for MIMO-OFDM simulation, where the implementation includes custom adjustments but currently exhibits high Bit Error Rate (BER) - seeking expert assistance for optimization and performance improvement
Detailed Documentation
This content references Wang Yumin's work "Key OFDM Technologies and Applications," which includes original source code for MIMO-OFDM system simulation. The implementation covers fundamental OFDM components such as IFFT/FFT operations, cyclic prefix insertion, and MIMO spatial multiplexing techniques. Personal modifications have been applied to the codebase, but performance analysis indicates significantly elevated Bit Error Rate (BER) metrics in the current implementation. The simulation likely involves channel coding (possibly convolutional or LDPC codes), QAM modulation schemes, and channel estimation algorithms. Seeking assistance from experienced communication systems engineers to debug and optimize the code structure, potentially through improved equalization techniques, better channel state information handling, or enhanced signal detection algorithms to achieve acceptable BER performance standards.
