Most important performance metrics commonly affected by radio wave propagation models are the received signal level and cochannel interference [6].

That is attribute to the cochannel interference and severe multipath as shown in Figure 4.
Due to the other simultaneously activated infrastructures and vehicles, the reception of D would be corrupted by cochannel interference so that a satisfactory quality of message delivery may not be attainable.
All of the above mentioned papers have significantly increased our knowledge of performance analysis of HSTCN, however they have concentrated on ideal case without cochannel interference (CCI).
In the overlap area, if channel allocation is not reasonable, it will cause interference problems when the terminals in the overlap area exchange data with the corresponding AP, especially when cochannel interference appears; it may even cause the communication interruption between client and its AP.
The performance study of conventional MRC receiver in the presence of cochannel interference has also been a substantial interest of researchers [19-24].
When adding a second user (cochannel interference), the EVM is 0.42 dB worse than a single user with different TFC.
In particular, we are interested in the case of densely populated sensor networks where, due to extensive frequency reuse, the cochannel interference (CCI) among sensor nodes and the cross-tier interference (between the macrocell and sensor networks) affect the system performance.
On one hand, to shorten the communication latency, node pairs are required to communicate concurrently as much as possible; on the other hand, concurrent transmissions induce the cochannel interference, which results in severe deterioration or even interruption of an ongoing transmission.
