Although spectral precoding is a propitious technique to suppress out-of-band emissions, it has detrimental impact on the system-wide throughput performance, notably, in high data-rate multiple-input multiple-output (MIMO) systems with orthogonal frequency division multiplexing (OFDM), because of (spatially-coloured) transmit error vector magnitude (TxEVM) emanating from precoding. The first co...

We prove that every semidefinite moment relaxation of a polynomial optimization problem (POP) with ball constraint can be reformulated as program involving matrix constant trace property (CTP). As result such relaxations solved efficiently by first-order methods exploit CTP, e.g., the conditional gradient-based augmented Lagrangian method. also extend this CTP-exploiting framework to large-scal...
