ASIC implementation and performance comparison of adaptive detection for MIMO-OFDM system

We consider application specific integrated circuit (ASIC) implementation of two detector algorithms for multiple- input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) systems. Higher data rate and lower power consumption requirements set new challenges for implementation. An optimal detector would be able to change the detection algorithm to suit the channel conditions in order to minimize the power consumption. The detectors are designed for 4 × 4 and 8 × 8 antenna systems and three different modulation schemes using 28 nm complementary metal oxide semiconductor (CMOS) technology. The performance of the chosen algorithms is evaluated in third generation (3G) long-term evolution (LTE) system.
