Digital Signal Processing IP Cores
Noesis Technologies offers an extensive library of signal processing cores. Discrete Fourier Transforms (DFT) are very common in OFDM based wireless applications as well as in many other telecom applications. The Fast Fourier Transform (FFT) algorithm provides an efficient method for DFT computations in real-time applications.
Noesis has developed a complete FFT/IFFT library that provides SoC designers with a range of high performance FFT cores for various target technologies. The cores are designed to be highly configurable, with optimized silicon efficient architectures that support complex sample rates up to 100 MS/s. A wide range of FFT lenghts from 8-point to 8K-points is supported.
Noesis offers state-of-the-art components used at PHY level of a transmission system. Our soft output demapper receives the equalized complex samples and converts them to a bit stream with soft output information associated with each bit. The probabilistic information is generated based on LLR computations. The core also supports multiple PSK and QAM modulation levels and programmable number of soft bits.
