Abstract

Based on the sequential sample rate conversion (SRC) structure using B-spline interpolation for orthogonal frequency division multiplexing (OFDM) based software defined radios, a parallel processing SRC structure is proposed in this paper to achieve high speed data transmission for multiband OFDM systems. By deriving an impulse response matrix from the sequential SRC structure, the state vectors of the SRC structure can be calculated from a block of input samples with less complexity than conventional Farrow structure. Real-time SRC implementation combined with local feedback and stuffing is also presented. Performance in terms of state buffer pointer offset caused by clock variation and finite precision in digital hardware is analyzed to provide guidance for practical system design such as determining clock stability and word-length requirements.
