Cooperation-based Interference Mitigation in Heterogeneous Cloud Radio Access Networks without Requiring CSI
Researchers have developed the development of a Heterogeneous Cloud Radio Access Network (HCRAN) consists of a Small Remote Radio Head (S-RRH) for the secondary users (Small Cell Users SUEs) and macro RRH for the primary users (multiple macrocell users MUEs), to meet the continuous increase in the number of mobile phone users and the change in traffic patterns. However, H-CRAN layers may overlap each other. Researches were able to reduce internal interference between RRHs through central collaborative processing in the BBU group. Layer interference between small RRHs cells (S-RRHs) and RRH Macrocell (RRH macros) was resolved by proposing a framework to reduce interference between Microcell networks and small cellular networks by suggesting a two-way collaborative algorithm. But they assumed that the channel status information (CSI) was available. This assumption makes no sense in the wireless communication environment, due to the possible interruption of specific ranges, which results in devices not obtaining or delaying the information. The study was also limited to fixed users or infantry subjects. They did not predict the movement of people moving at high speeds. In this paper, we will use the frequency hopping (FH) orthogonal frequency division multiplexing-aided differential chaos shift keying (OFDM-DCSK) modulation to overcome an inaccurate or unknown CSI problem, In addition to the ability to predict the movement of users who move between cells, and provide services within the cell in which the user is located.
