IEEE/ICACT20260352 Question.1 Questioner: qga0809@chungbuk.ac.kr 2026-02-09 오후 2:04:31	IEEE/ICACT20260352 Answer.1 Answer by Auhor lee19711936516@163.com 2026-02-09 오후 2:04:31
Your simulation shows that the MIMO-OCDM signal achieved a maximum detection distance of 34.71m while reducing the interception distance. How does the system performance change when the number of sub-chirp signals increases beyond 8, and is there an optimal number of sub-chirp signals for balancing detection range and low interception performance?	Firstly, thank you for your question. When the number of sub chirp signals exceeds 8, the low interception performance of the system will improve. However, as the number of sub chirp signals increases, the difficulty of signal processing also increases. The reason for choosing 8 sub chirp signals is based on a comprehensive consideration of detection distance and signal processing difficulty.
