Detection techniques for massive multiple-input multiple-output (MIMO) have gained a lot of
attention in both academia and industry. Detection techniques have a significant impact on …

This thesis addresses theoretical, mathematical modelling and design issues of Spectrally
Efficient FDM (SEFDM) systems. SEFDM systems propose bandwidth savings when …

Non-orthogonal Spectrally Efficient Frequency Division Multiplexing (SEFDM) signals of a
small dimensionality can be optimally detected using the Sphere Decoder (SD) algorithm …

This thesis considers theoretical, analytical and engineering design issues relating to non-
orthogonal Spectrally Efficient Frequency Division Multiplexing (SEFDM) communication …

In this paper, we evaluate the uplink bit error rate (BER) of multicarrier-code-division-
multiple-access (MC-CDMA) cellular systems with multiuser-maximum-likelihood detector …

In this paper, a computationally efficient implementation technique for optimal precoder
selection in spatially multiplexed (SM) multiple-input multiple-output (MIMO) systems with …

We propose a low-complexity, complex-valued sphere decoding (CV-SD) algorithm, which
is referred to as circular sphere decoding (CSD) and is applicable to multiple-input-multiple …

One of the forms for Sphere Decoding (SD) requires the computation of Zero Forcing (ZF)
solution, which in turn demands a matrix inversion. It is already known that the application of …

In this paper, we study the diversity-multiplexing tradeoff assuming groupwise successive
interference cancelation (GSIC). GSIC with layered codes in multiple-input multiple-output …

The sphere decoding (SD) is a category of algorithms finding the closest lattice point and
known to have the expected complexity approximately cubic in the dimension of the lattice …
