Flexible Gaussian Minimum Shift Keying in Cellular Mono Internet System

摘要

Methods, systems and devices for wireless communication at a UE are described. User equipment (UE) uses orthogonal frequency division multiple access (OFDMA) to demodulate downlink messages and uses a combination of GMSK and single carrier frequency division multiple access (SC-FDMA) for uplink modulation can do. The uplink modulation process is filtered using M-point discrete Fourier transform (DFT) to generate the symbol vector, filtering the symbol vector using a frequency domain Gaussian filter, and using inverse DFT. Generating a sample vector from the symbol vector and modulating the sample vector using GMSK can be included. In some cases, the uplink modulation may be based on a narrowband resource allocation received from the base station.
