摘要

In this paper, a hardware efficient multiple-input multipleoutput (MIMO) detector which flexibly supports multiple antenna configurations (2 × 2, 4 ×4 and 8× 8)) and data modulations (QPSK, 16- QAM and 64-QAM) is presented. A breadth-first decoding algorithm known as distributed K-best (DKB) is applied in this design. The DKB greatly reduces required visiting nodes and excludes sorting operation at each layer to save computing complexity. The proposed antenna configurable pipelined multi-stage architecture is composed of elementary function blocks of DKB. Each DKB blocks requires only K clock cycles to find the best K candidates, where K denotes the number of calculated survival paths. The proposed MIMO detector has been implemented by a 90-nm CMOS technology with the core area of 1.014 mm2. The average power consumption is 17.76 mW when operates at the maximum frequency of 74 MHz and 1 V power supply voltage.
