Um esquema de demodulação digital não coerente é apresentado para recepção de sinais Gaussianos de modulação por deslocamento de frequência (GFSK) com pequeno índice de modulação. O demodulador diferencial proposto utiliza sinais sobreamostrados para estimar o tempo do símbolo e compensar o deslocamento de frequência. O desempenho do receptor proposto é avaliado em termos da taxa de erro de bit (BER). Os resultados numéricos mostram que o demodulador proposto fornece desempenho comparável ao do demodulador diferencial de banda base convencional, ao mesmo tempo que reduz significativamente a complexidade de implementação adequada para integração de chip único com módulo de conversão direta de radiofrequência. Finalmente, o desempenho do receptor proposto é melhorado com a adição de um módulo simples de feedback de decisão.

Abstract: A digital noncoherent demodulation scheme is presented for reception of Gaussian frequency shift keying (GFSK) signals with small modulation index. The proposed differential demodulator utilizes oversampled signals to estimate the symbol timing and to compensate the frequency offset. The performance of the proposed receiver is evaluated in terms of the bit-error rate (BER). Numerical results show that the proposed demodulator provides performance comparable to that of conventional baseband differential demodulator, while significantly reducing the implementation complexity suitable for single chip integration with direct conversion radio frequency module. Finally the performance of the proposed receiver is improved by adding a simple decision feedback module.
