摘要：
This paper presents an SDR based digital receiver of automatic identification system (AIS) which is suitable for micro-nano satellites. A multi-channel digital processing structure based on SoC is proposed, and an improved blind source separation (BSS) algorithm is used to separate collided signals from different SOTDMA zones. Test results show that the proposed receiver not only achieve high performance but also has compact size and low power consumption.
