| Abstract(in English) | This report presents a low power architecture that dynamically controls a wordlength in a wireless OFDM demodulator. Finding the optimum wordlength for digital circuit systems is a difficult issue since the trade-off between hardware cost and system performance is not conclusive. We propose a tunable wordlength architecture (TWA) that dynamically changes its own wordlength according to optimum communication environments. The proposed OFDM receiver measures error vector magnitude (EVM) from de-modulated signals and tunes a wordlength to satisfy the required quality of communication by monitoring the EVM performance. Our result reports that the demodulator can reduce dissipated energy by a maximum of 32% and 24% in AWGN and multipath fading channels, respectively. |
