PA Nonlinearity and Power Allocation in CRN

Helen Achankunju

In the resource allocation of the cognitive radio network the interference to the primary receiver is a critical issue. For instance the power amplifier nonlinearity causes nonlinear interference to the primary receivers. Consider the nonlinear effects of the power amplifier on the received SNR at the secondary receiver and the adjacent channel interference at the PR. To calculate the throughput an analytical expression is derived for the probability of data transmission between the secondary users and the primary receivers. Performance and analysis are based on the both the peak and average power constraints. Through knowledge about theoretical analysis and simulation results, maximum achievable average SNR is calculated.
