N2 - Backscatter communication has evolved, but the research interest has predominantly focused on a single carrier radio frequency source. In this paper, we propose a joint Repetition Coding (RC) and Multi-Source Temporal Combining (TC) framework to enhance the reliability and throughput of backscatter communication. Unlike conventional approaches that rely on a single carrier source or uniform repetition coding, our method dynamically assigns position-aware repetition codes while leveraging multiple ambient RF sources to exploit temporal diversity. We developed an analytical model to evaluate the bit error rate (BER) performance under different coding strategies and source distributions. Furthermore, we derive a closed-form optimization framework for adaptive weight allocation in TC, ensuring that the contribution of each RF source is weighted based on SNR, coherence time, and estimated BER.
