Unified Error Rates Analysis of MIMO Space-Time Block Codes over Generalized Shadowed {\kappa}-{\mu} and {\eta}-{\mu} Fading and AWGGN
This paper presents a novel unified performance analysis of Space-Time Block
Codes (STBCs) operating in the Multiple Input Multiple Output (MIMO) network
and subjected to generalized shadowed fading and noise scenarios. Specifically,
we derive novel, simple and accurate average bit error rates (ABER) expressions
for coherent modulation schemes in the generalized {\eta}-{\mu} and shadowed
{\kappa}-{\mu} fading channels. The noise in the network is assumed to be
modeled by the additive white generalized Gaussian noise (AWGGN), which
encompasses the Laplacian and the Gaussian noise environments as special cases.
The result obviates the need to re-derive the error rates for MIMO STBC systems
under many multipath fading and noise models, while avoiding
computationally-expensive expressions. Published results from the literature as
well as numerical simulations corroborate the accuracy of our derived
generalized expressions
Error Rates Analysis of MIMO Space-Time Block Codes in Generalized Shadowed Fading Channels
This paper introduces a new and unified bit error rates performance analysis
of space-time block codes (STBC) deployed in wireless systems with spatial
diversity in generalized shadowed fading and noise scenarios. Specifically, we
derive a simple and a very accurate approximate expressions for the average
error rates of coherent modulation schemes in generalized and
shadowed fading channels with multiple input multiple output
(MIMO) systems. The noise in the network is assumed to be modeled using the
additive white generalized Gaussian noise (AWGGN), which encompasses the
classical Laplacian and the Gaussian noise environments as special cases. The
derived results obviate the need to re-derive the error rates for MIMO STBC
systems under many multipath fading and noise conditions while avoiding any
special functions with high computational complexity. Published results from
the literature, as well as numerical evaluations, corroborate the accuracy of
our derived generalized expressions.Comment: Accepted in Advances in Wireless and Optical Communications (RTUWO),
