Este artigo apresenta um método de estimativa de canal auxiliado por piloto que é particularmente adequado para o modo WiMAX 802.16e Downlink Partial Usage of Subchannel móvel. Com base neste modo, vários métodos comumente usados de estimativa de canal são estudados e o método de ajuste de linha de mínimos quadrados é proposto. À medida que os dados dos usuários são distribuídos em grupos permutados de subportadoras no símbolo OFDMA transmitido, o método de estimativa de canal proposto utiliza essas vantagens para fornecer melhor desempenho do que as abordagens convencionais, ao mesmo tempo que oferece complexidade notavelmente baixa na implementação prática. Os resultados da simulação com diferentes canais ITU para ambientes móveis mostram que dependendo das situações, pode ser alcançado um aumento de 5 dB ou mais em termos de SNR.

Abstract: This paper presents a pilot-aided channel estimation method which is particularly suitable for mobile WiMAX 802.16e Downlink Partial Usage of Subchannel mode. Based on this mode, several commonly used channel estimation methods are studied and the method of least squares line fitting is proposed. As data of users are distributed onto permuted clusters of subcarriers in the transmitted OFDMA symbol, the proposed channel estimation method utilizes these advantages to provide better performance than conventional approaches while offering remarkably low complexity in practical implementation. Simulation results with different ITU-channels for mobile environments show that depending on situations, enhancement of 5 dB or more in term of SNR can be achieved.
