“…The PDF of the SINR, denoted as f Y , is derived in as

“…Recently, several studies have been conducted to solve the problem of ACI mainly for the LTE system. Among the studies conducted on ACI within an LTE network, Son and Kim show that an adjacent channel interference ratio (ACIR) of at least 46 dB is required to prevent the occurrence of interference between the uplink channel from a mobile station and the downlink channel from a base station. To secure the reliability between vehicle‐to‐vehicle (V2V) communication devices using LTE, it has been proposed that the interference can be reduced through the scheduling of the resource block, transmission power, and modulation scheme as described in .…”

“…An accurate ACI model is required when analyzing the performance of ACI through a numerical analysis or simulation. The ACI model derivation and performance analysis has been presented in . Firstly, in the study of the ACI model using the distribution functions , the signal‐to‐interference‐plus‐noise ratio (SINR) equation was obtained by considering the co‐channel and adjacent channel interference signals from multiple terminals using the same LTE network, and the ACI model was derived by using the probability density function (PDF) that was derived from the SINR equation.…”

Many use cases have been presented on providing convenience and safety for vehicles employing wireless access in vehicular environments and long‐term evolution communication technologies. As the 70‐MHz bandwidth in the 5.9‐GHz band is allocated as an intelligent transportation system (ITS) service, there exists the issue that vehicular communication systems should not interfere with each other during their usage. Numerous studies have been conducted on adjacent interfering channels, but there is insufficient research on vehicular communication systems in the ITS band. In this paper, we analyze the interference channel performance between communication systems using distribution functions. Two types of scenarios comprising adjacent channel interference are defined. In each scenario, a combination of an aggressor and victim network is categorized into four test cases. The minimum requirements and conditions to meet a 10% packet error rate are analyzed in terms of outage probability, packet error rate, and throughput for different transmission rates. This paper presents an adjacent channel interference ratio and communication coverage to obtain a satisfactory performance.
