  • Abstract
    The physical random access channel (PRACH) of a mobile hotspot network (MHN) is based on a single carrier frequency division multiple access (SC-FDMA). In this paper, we introduce a practical filter design of interpolation-based SC-FDMA transmitter for random access preamble generation. A multistage interpolation filter is used to increase the preamble sampling rate of 12.96 MHz to the system sampling rate of 184.32 MHz, while lowering the sidelobes below -60 dB. In the implementation point of view, this interpolation-based PRACH transmitter provides efficiency and reduction in complexity.
