Ansoft announces an ultra-wideband (UWB) design library for designers of multiband orthogonal frequency division multiplexed (OFDM) radio systems. The kit, for use with Ansoft Designer®, allows engineers to generate and detect Multiband OFDM Alliance (MBOA)-compliant OFDM waveforms for system- and circuit-level simulations. In addition, users can perform dynamic co-simulations with detailed, transistor-level descriptions of analog and mixed-signal blocks using Ansoft's Nexxim® circuit simulator. The library enables Ansoft Designer users to simulate all analog and DSP functions in the MBOA transmitter and receiver. Engineers can use the library to generate and detect MBOA-compliant waveforms and apply them at the behavioral level, the transistor circuit level or both. Bit- and frame-accurate models for DSP blocks like the scrambler, convolutional encoder, puncturer, bit interleaver, constellation mapper, and FFT processor, have all been implemented in the library.
