Tanto a modulação adaptativa quanto a combinação de diversidade são técnicas atraentes para combater o desvanecimento e estas duas podem ser aplicáveis a cada símbolo modulado digitalmente na transmissão OFDM. Nesta carta, visando combater o desvanecimento severo de forma mais eficaz do que a modulação adaptativa, analisamos teoricamente o benefício de um esquema de diversidade de frequência dentro de um símbolo OFDM, que é um tipo simples de OFDM codificado (COFDM) baseado nos protocolos IEEE 802.16. Uma equação simples de forma fechada de taxa de erro de bit (BER) é derivada e, em seguida, as vantagens do ganho de diversidade correlacionado e da supressão de interferência pelo esquema de diversidade são verificadas tanto pela análise teórica quanto pela simulação de Monte Carlo.

Abstract: Both adaptive modulation and diversity combining are attractive techniques to combat fading and these two can be applicable to each digital-modulated symbol in OFDM transmission. In this letter, aiming to combat severe fading more effectively than the adaptive modulation, we theoretically analyze the benefit of a frequency diversity scheme within one OFDM symbol, which is a simple kind of coded OFDM (COFDM) based on IEEE 802.16 protocols. A simple closed form equation of bit error rate (BER) is derived, and then the advantages of correlated diversity gain and interference suppression by the diversity scheme are verified by both theoretical analysis and Monte Carlo simulation.
