Tensor based modelling for GFDM

Fifth generation cellular communication standard supports number of implementation scenarios, which change main communication quality of service criteria's. Huge number of different presets dependent to the used case increase requirements to the 5G's physical layer. As example in the physical layer of 5G are allowed such kind of technologies as MIMO, spectrum sensing, out-of-band emission decreasing, and white space. Generalized frequency division modulation is used as the modulation scheme in the 5G. Generalized frequency division modulation allows adapting for the current situation in the frequency space. In this article we will introduce algorithm for simultaneous activated subcarriers and symbols search in the white space scenario.
