Sphere Decoder for Massive MIMO

Modern wireless communication systems demanding high data rate operating in bandwidth deficient world is using Multiple Input Multiple Output (MIMO) antenna arrangement. MIMO arrangement helping achieving high data rates with a technique of special multiplexing saves bandwidth but needs efficient receivers with manageable hardware. The receivers employing linear equalizers or Decision Feedback ...

Efficient List Decoder for Algebraic-Geometric Codes

A list decoder can outperform the conventional unique decoder by giving a list of transmitted message candidates and can be applied to Reed-Solomon (RS) codes and algebraic-geometric (AG) codes. This paper presents the first efficient list decoder which is developed from the framework of the GuruswamiSudan (GS) algorithm for AG codes. Fast implementation methods for the algorithm’s key processe...

Hierarchical Sparse Channel Estimation for Massive MIMO

The problem of wideband massive MIMO channel estimation is considered. Targeting for low complexity algorithms as well as small training overhead, a compressive sensing (CS) approach is pursued. Unfortunately, due to the Kroneckertype sensing (measurement) matrix corresponding to this setup, application of standard CS algorithms and analysis methodology does not apply. By recognizing that the c...

Is Massive MIMO Energy Efficient?

Massive multi-input multi-output (MIMO) can support high spectral efficiency (SE) with simple linear transceivers, and is expected to provide high energy efficiency (EE). In this paper, we analyze the EE of downlink multi-cell massive MIMO systems under spatially correlated channel model, where both transmit and circuit power consumptions, training overhead, channel estimation and pilot contami...
