Research output: Contribution to journalArticlepeer-review


We propose a cost-efficient symbol detection scheme, which removes complex functional blocks requiring high hardware complexity and computation power, for MIMO-OFDM systems adapting an SDM technique. In order to reduce the complexity, we modify the conventional approach of symbol detection with maintaining the equivalence between the original and modified equations. From the implementation results, the proposed symbol detector reduces the hardware complexity by 18.2% compared to a conventional symbol detector, and can be a good solution for the low hardware complexity design of SDM-OFDM systems.
