The analytical expressions for the performance metrics of wireless networks usually take a very complicated form that inhibits quick useful insights. We are working on a unified approach to obtain rational function approximations in all SNR regions.
Completed work include the analysis of average error rate analysis of MIMO, relay systems,probability of detection of cognitive radio systems, block error rates. We now expect to use these result to improve resource allocation methods in wireless networks.
The analytical expressions are sometimes not derivable due to the unavailability of closed form results for the required integrals. Quadrature methods are a well known tool to perform numerical integration in these scenarios. We are working on improving these quadrature methods to achieve higher accuracy with lesser number of terms(i.e. less computation complexity)
