Iterative Reconfigurable Tree Search Detection of MIMO Systems
This paper is concerned with reduced-complexity detection, referred to as iterative reconfigurable tree search (IRTS) detection, with application in iterative receivers for multiple-input multiple-output (MIMO) systems. Instead of the optimum maximum a posteriori probability detector, which performs brute force search over all possible transmitted symbol vectors, the new scheme evaluates only t...
متن کاملGeneralized Smart Candidate Adding for Tree Search Based MIMO Detection
Tree search schemes are an efficient means of solving the detection problem in MIMO systems. There exist two fundamentally different approaches when using such techniques for soft output detection. The traditional way is to employ a single undirected search to generate a list of hypotheses on the transmit signal. Alternatively, multiple directed searches can be used – Smart Candidate Adding. Th...
متن کاملLow Complexity Detection using Likelihood Based Tree Search for Large MIMO Systems
A low complexity detection algorithm for Large MIMO systems is presented using a Likelihood based tree search algorithm. It outperforms the controlled Branch and Bound algorithm, which itself performs much better than other heuristic techniques for detection in Large MIMO systems. A novel metric is used for tree branching and the computational complexity is considerably reduced using various tr...
متن کاملReconfigurable Antennas in mmWave MIMO Systems
The key obstacle to achieving the full potential of the millimeter wave (mmWave) band has been the poor propagation characteristics of wireless signals in this band. One approach to overcome this issue is to use antennas that can support higher gains while providing beam adaptability and diversity, i.e., reconfigurable antennas. In this article, we present a new architecture for mmWave multiple...
متن کاملIterative Transceiver Optimization for Multiuser MIMO Systems
We consider the uplink of a multiuser system where the transmitters as well as the receiver are equipped with multiple antennas. Each user multiplexes its symbols by using a linear precoder through its transmit antennas. We work with the system-wide mean squared error as the performance measure and propose algorithms to find the jointly optimum linear precoders at each transmitter and linear de...
