Abstract: A transmitter includes a processor configured to convert a primary sequence of modulation symbols into a primary signal using a universal pulse shape. The processor is further configured to convert an auxiliary sequence of modulation symbols, created from the primary sequence, to an auxiliary signal using an altered version of the universal pulse shape. In addition, the processor is configured to combine the primary signal and the auxiliary signal to create a joint output signal.

Abstract: An apparatus for band-limited frequency division multiplexing for uplink transmission to a base station or access point, particularly from an IoT device, comprises a signal modulator to transmit a signal over a set of contiguous equally spaced frequency sub-carriers ranging from a lowest frequency sub-carrier via intermediate sub-carriers to a highest frequency sub-carrier. The signal modulator contains a filter to apply asymmetric filtering over the range of the frequency sub-carriers, thereby to reduce a peak-to-average power ratio of the transmitted signal.
