Investigating binary coded excitation schemes for US wearables with low-complexity electronics

In comparison to high‑end clinical ultrasound (US) scanners, wearable and miniaturized US systems are constrained by power consumption, computational resources, and hardware complexity, making it difficult to maintain high signal quality at low transmit energy. To improve the signal quality and address the trade‑off between signal‑tonoise ratio (SNR) and energy efficiency, we investigated binary‑coded excitation combined with pulse compression (PC) on a resource‑constrained microcontroller platform. Our findings confirm that embedded binary‑coded excitation is a viable strategy for enabling high‑perfor mance, energy‑efficient US wearables.
