In recent times, there have been significant advancements in utilizing the sensing capabilities of mobile devices for developing applications. The primary objective has been to enhance the way a user interacts with the application by making it effortless and convenient. This paper explores the capabilities of using Brain computer Interfaces (BCI), an evolving subset of Human computer Interaction (HCI) paradigms, to control mobile devices. We present a comprehensive survey of the state-of-the-art in this area, discussing the challenges and limitations in using BCI for mobile applications. Further we propose possible modalities that in future can benefit with BCI applications. This paper consolidates research directions being pursued in this domain, and draws conclusions on feasibility and benefits of using BCI systems effectively augmented to the mobile application development domain.

In this paper, the serial interference cancellation(SIC) is discussed from 3 G, 4 G typical application technologies(DS-CDMA, MIMO-OFDM) and non-orthogonal multiple access(NOMA) which is 5 G candidate technology. We also simulate the SIC algorithm in the related technologies. The results show that SIC technology is concerned by domestic or foreign scholars and the research of SIC technology is more profound with the development of wireless communication technology. SIC technology is improved to adapt different communication system requirements are the development direction of the technology in the pursuit of optimal performance. First of all, the performance of the SIC receiver is better than traditional receiver in the DS-CDMA system. Then the first simulation compares the algorithms of ZF, MMSE, ZF-SIC, MMSE-SIC, ZF-OSIC, MMSE-OSIC in the MIMO-OFDM and MMSE-OSIC has the best performances among of them. Finally, the SIC receiver is used to improve the spectral efficiency of the NOMA system. The more efficient and simpler SIC receiver is the key of NOMA technology in the 5 G technology.
