| Abstract(in English) | In the next generation mobile radio communication systems, it is essential to obtain the communication environment information accurately and quickly in order to implement appropriate control such as adaptive modulation and coding for realizing high-speed, high-capacity and low-delay communication. SNR, Doppler shift, and $K$-factor are some of the communication environment parameters that have a significant impact on the performance of adaptive modulation and coding. In the past, it has been difficult to introduce these parameters into adaptive modulation and coding for high-speed and large-capacity communications because the estimation of these parameters requires a huge amount of computation, a reference signal, and large-scale signal sampling. In this paper, we propose a method for estimating these multiple communication environment parameters on a per-packet basis without using reference signals by using convolutional neural networks from spectrogram images of the received signal. From the simulation results, we clarify the effectiveness of the proposed method in terms of the estimation accuracy of SNR, Doppler shift, and $K$-factor when they are estimated independently and the estimation accuracy when these three parameters are estimated simultaneously. |
