Resource Overview

Comparative analysis of OFDM spectrum diagrams with and without windowing, including overlapping vs non-overlapping cyclic prefix scenarios, with additional BER calculation methodology and implementation details.

Detailed Documentation

This article provides a detailed analysis comparing OFDM spectrum diagrams before and after windowing implementation. We examine two distinct scenarios: cyclic prefix overlapping versus non-overlapping configurations, with comprehensive comparative evaluation. Furthermore, we present the methodology for calculating Bit Error Rate (BER) including specific computational approaches. Through detailed discussion of windowing techniques and their impact on spectral characteristics, readers will gain better understanding of OFDM performance differences and enhanced capability for system performance evaluation. The analysis includes considerations for practical implementation using signal processing functions such as Hanning/Hamming windows for spectral shaping and FFT operations for frequency domain transformation.
