Query: Joint Resource Allocation for OFDMA based Overlay Cognitive Radio
  Networks under Stochastic Rate Constraint   This work presents joint subcarrier, power and bit allocation schemes for
multi-user OFDM based overlay cognitive radio under constraints on primary user
throughput loss and total secondary user transmitted power. Closed form for
expressions for the optimal power and bit allocations are initially derived.
Subsequently, optimal and suboptimal algorithms to realise the joint
subcarrier, power and bit allocations are introduced. Numerical simulations are
used to evaluate the performance of the joint resource allocation algorithms.
