Modern wireless communication standards define new high-throughput use cases like 8 $\times$ 8 multiple-input, multiple-output (MIMO) antenna setups and a 256-QAM constellation alphabet in the case of IEEE 802.11ac. Baseband precoding at the transmitter is a key technique to achieve the corresponding data rates at a reasonable signal-to-noise ratio (SNR). Multimode capability, (i.e., the ability...
This paper investigates the possibility of creating an energy profile of a RISC processor instruction set in the prototyping phase, using FPGA implementation and physical measurements. In order to determine the power consumption at instruction-level, several programs have been developed and run on the processor implementation on FPGA. The experiments have focused at the following groups of instructions:...
A computational complexity analysis of matrix inversion used in soft-input soft-output minimum mean square error (MMSE) MIMO detectors and a comprehensive literature comparison of corresponding VLSI implementations are presented. They indicate that the application specific integrated circuit (ASIC) proposed in this paper is — to the best of our knowledge — the most area-throughput efficient VLSI architecture...
A novel reduced-complexity soft-input soft-output minimum mean square error detection algorithm for MIMO systems together with an area-throughput efficient VLSI architecture is described. A detailed comparison to related work is presented. The proposed VLSI architecture of the novel algorithm represents — to the best of our knowledge — the most area-throughput efficient SISO MIMO detector ASIC reported...
