摘要
The performance of equalization techniques for digital radio systems in the presence of sinusoidal and modulated interference signals are investigated. Linear and nonlinear equalizers, as well as synchronous and T/2-spaced structures are considered. It is shown that i) synchronous decision-feedback equalizers are powerful countermeasure devices for radio channels affected by both selective fading and sinusoidal interferers; ii) both T/2-spaced linear and nonlinear equalizers can provide a significant improvement of the adjacent channel interference margin, whether the channel is selective or not, especially in the case of multicarrier interleaved frequency arrangements.
