MIMO detection in analog VLSI

—In this paper we propose an analog VLSI approach to maximum a posteriori (MAP) detection in Multiple-Input Multiple-Output (MIMO) systems. This detector can be seen as an extension of the well known analog decoding concept for error correcting codes, as it is constructed using similar building blocks. Therefore, it can naturally interact with analog decoders in order to perform turbo detection in MIMO systems. First transistor-level simulations for a small analog MIMO detector in a 0.25µm BiCMOS process agree well with floating-point digital simulations.
