MOBILE TERMINAL DEVICE AND METHOD FOR PROCESSING SIGNALS

摘要

A mobile terminal device may include a radio processing circuit and a baseband processing circuit adapted to interact with the baseband processing circuit. The mobile terminal device may be configured to calculate a plurality of inverse frequency transforms with inputs of a plurality of samples of a frequency-domain signal sequence to generate a plurality of intermediate transforms, wherein each of the plurality of intermediate transforms are composed of a respective plurality of samples, combine the respective plurality of samples of each of the plurality of intermediate transforms to generate a time-domain representation of the frequency-domain signal sequence, generate a random access preamble with the time-domain representation of the frequency-domain signal sequence, and transmit the random access preamble.
