Integrated sensing and communication (ISAC) technology is a promising candidate for next-generation communication systems. However, severe co-site interference in existing ISAC systems limits the communication and sensing performance, posing significant challenges for ISAC interference management. In this work, we propose a novel interference management scheme based on the normalized least mean square (NLMS) algorithm, which mitigates the impact of co-site interference by reconstructing the interference from the local transmitter and canceling it from the received signal. Simulation results demonstrate that, compared to typical adaptive interference management schemes based on recursive least square (RLS) and stochastic gradient descent (SGD) algorithms, the proposed NLMS algorithm effectively cancels co-site interference and achieves a good balance between computational complexity and convergence performance.

This paper proposes that the business model of mobile Internet services is shifting from a walled garden to an open one. The service development model relies more on open Application Programme Interface (API ); and the online application software store is becoming an important platform for service delivery. The terminal platform has been the commanding point of the layout and competition of the mobile Inernet in the world. Based on the smart terminal, the competition for platform system from the hardware platform to the operation system, the middleware and the applications platform have been in shape globally. The competition in the terminal platform of mobile Internet is moving from close to open, from uni-controlled by one company to open and cooperated by the whole industry. China should forge a terminal platform system and the ecosystem for the mobile Internet industry, and seek to achieve an overall breakthrough in the whole value chain of the industry based on the huge mobile user market and the productivity of the terminal. The breakthrough should start from the application software, stepping from the top to the bottom platform, to extend the industry chain.
