- Abstract:
- This paper analyzes the effect of analog-to-digital bandpass Sigma-Delta conversion on the performance of Orthogonal Frequency Division Multiplexing (OFDM) systems. A brief description of both OFDM systems and the related simulation model is given. The nonlinear effects of quantization overload on overall OFDM performance are evaluated in terms of quantization noise power and bit error rate. It is shown how minimizing quantization noise power can lead to suboptimal results. Moreover a set of minimum performance requirements for Sigma-Delta converters is established.
