This paper describes a modular hardware platform of a multi-user (MU) multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) testbed. The hardware platform is based on multiple field programmable gate arrays (FPGAs), provides four integrated radio-frequency (RF) chains, and has capabilities for extension boards. The(More)
We consider the problem of block-coded communication, where in each block, the channel law belongs to one of two disjoint sets. The decoder is aimed to decode only messages that have undergone a channel from one of the sets, and thus has to detect the set which contains the underlying channel. We begin with the simplified case where each of the sets is a(More)
This paper provides an overview of a real-time multi-user multiple-input multiple-output (MIMO) communication testbed designed for demonstration and assessment of real-world wireless communication aspects. The testbed is built on a modular hardware platform consisting of three different boards and incorporates a MIMO-OFDM-based physical (PHY) layer, an(More)
