Abstract(in English) | This presents power reduction for MIMO-OFDM receiver circuits using dynamic MIMO detection techniques. MIMO-OFDM imposes MIMO detection to separate received signals multiplexed in the transmitter, however MIMO detection has huge amount of computations, which increases power consumption. To solve this, we propose a technique to reduce power consumption by introducting dynamic MIMO detection and dynamic voltage and frequency scaling (DVFS). Dynamic MIMO detection computes the weight matrix across multiple packets. A DVFS technique gives a dynamic operating voltage and frequnency to the MIMO detector circuit. This circuit has been implemented in to pipelined MMSE detector curciuts developed in our previous studies. We report the evaluation results in communication performance and power consumption. |
