Abstract
This paper describes the implementation of a multi-mode MIMO detector based on the concept of partially reconfigurable ASIP (rASIP). The multi-mode detector can support three different detection algorithms which are the Maximum Ratio Combining, the linear Minimum Mean Square Error (MMSE) detection, and the MMSE Successive Interference Cancellation. The detection algorithms also support different antenna configurations and modulation schemes. The rASIP is based on a Coarse-Grained Reconfigurable Architecture (CGRA), which is designed for efficient architectural support of matrix operations. A matrix inversion algorithm, which is used for the preprocessing of different detection algorithms, is mapped on the CGRA. By integrating a processor with the CGRA, the variations in the control path of different algorithm configurations can be handled efficiently. To the best of our knowledge, we show, for the first time that, a CGRA-based multi-mode MIMO detection is extremely efficient and matches the performance of dedicated ASIC implementation.
