Latest Patents

Interleaving Method in OFDM System. This invention describes an interleaving method designed to reduce transmission errors at the receiving end of an Orthogonal Frequency Division Multiplexing (OFDM) system. Data bits are stored in interleaving memory and read in a predetermined sequence to perform symbol interleaving, tone interleaving, and cyclic shifting simultaneously. The method also simplifies system logic by applying FFT mapping to the interleaver’s output before modulation.

FFT Apparatus for High Data Rate and Method Thereof. This invention presents an apparatus and method for processing input signals quickly during FFT operations. Four N/4-point FFT units, implemented using radix-2 single-path delay feedback (R2SDF) units, process the input signals in parallel. A radix-4 computation unit then processes signals transferred from those FFT units, enabling faster handling of high data rates.
