| Abstract(in English) | Device-to-device (D2D) communication allows user terminals to directly communicate with each other without the need for any base stations (BSs). Since the D2D communication underlaying a cellular system shares frequency channels with BSs, co-channel interference may occur. Successive interference cancellation (SIC), which detects and subtracts user signals from received signals in descending order of received power, can cope with the above interference and has already been applied to fog nodes that manage communications among machine-to-machine (M2M) devices besides direct communications with BSs. When differences among received power levels of user signals are negligible, however, SIC cannot work well and thus causes degradation in bit error rate (BER) performance. To solve such a problem, this report proposes to apply parallel interference cancellation (PIC), which can simultaneously detect both desired and interfering signals under the maximum likelihood criterion and can outperform SIC irrespective of channel conditions even when power level differences among users are small. Computer simulations show that PIC can achieve 10% higher average system throughput than that of SIC. As for transmission delay time, it is demonstrated that PIC can shorten the delay time more than any other schemes, although the fog node causes the delay time of 1 ms at least. |
