On frequency domain Channel estimation using WARP v3 hardware platform

Abstract

Multi antenna wireless systems, which is generally termed as multi-input multi-output (MIMO) systems offers greater channel capacity and reliability compared to the single-input single-output (SISO) systems. It is important for the system to know the channel state information (CSI) for exploiting better performance of the communication system. The instantaneous CSI is acquired in an indoor scenario using the hardware setup. In this paper we use WARP v3 kit to extract the CSI with Orthogonal frequency division multiplexing (OFDM) and without OFDM.
