Query: On Multihop Weibull-Fading Communications: Performance Analysis
  Framework and Applications   The paper presents a comprehensive closed-form performance analysis framework
for multihop communications over Weibull fading channels. The analyzed scheme
consists basically of multiple regenerative relays with generalized high-order
quadrature amplitude modulation (M-QAM) transmissions. To take into
consideration the channel fading in the mmWave range, we adopt the advocated
Weibull model for its flexible ability to cover different channel conditions.
The end-to-end performance is evaluated in terms of outage probability, bit
error probability (BER), symbol error probability (SER), block error rate
(BLER), ergodic capacity, and energy efficiency (EE). For all the metrics, we
present exact closed-form expressions along with their asymptotic behavior,
some in terms of generalized hypergeometric functions. Based on the obtained
analytical results, we also present a practical application, we derive two BER-
and EE-optimal transmit power allocation strategies, and we discuss the
resulting performance gains. The exactness of our analysis is illustrated by
numerical examples, and assessed via Monte-Carlo simulations for different
system and channel parameters. Finally, as a secondary contribution, noting the
increasing popularity of Fox's H and bivariate H functions, we provide new and
generalized codes for computing these functions which are of practical utility
in different contexts.
