Next-generation wireless networks aim at providing substantial improvements in spectral
efficiency (SE) and energy efficiency (EE). Massive MIMO has been proved to be a viable …

In sixth-generation (6G) communication networks, ultrahigh-data rate and reliability are
greatly vital for massive user connections and network sensors, such as Internet of Things …

It is well known that for Gaussian channels, a nearest neighbor decoding rule, which seeks
the minimum Euclidean distance between a codeword and the received channel output …

We present a novel closed-form lower bound on the Gaussian-input mutual information for
noncoherent communication (ie, in which neither transmitter nor receiver are cognizant of …

As shown by Médard, the capacity of fading channels with imperfect channel-state
information (CSI) can be lowerbounded by assuming a Gaussian channel input and by …

A well-established capacity lower bound of multiple-input multiple-output (MIMO) single-user
fading channels operating with imperfect receiver-side channel-state information (CSI) is …

For fast-fading memoryless single-user channels, we present new rate expressions that are
achievable with iid Gaussian codes and successive nearest-neighbor decoders based on a …
