Este artigo propõe um novo esquema de medição de erro vetorial para sistemas de multiplexação por divisão ortogonal de frequência (OFDM) que é usado para definir a precisão da modulação de transmissão. A precisão da modulação de transmissão é definida para garantir a interoperabilidade entre terminais sem fio. Nos sistemas OFDM, a precisão da modulação de transmissão medida pelo esquema convencional de medição de erro vetorial não pode garantir a interoperabilidade devido ao efeito do ruído de fase. Para superar este problema, o esquema de medição de erro vetorial proposto utiliza sinais piloto em múltiplos símbolos OFDM para compensar a rotação de fase causada pelo ruído de fase. Os resultados da simulação computacional mostram que o erro vetorial medido pelo esquema proposto corresponde exclusivamente à degradação C/N na taxa de erro do pacote, mesmo que exista ruído de fase nos sinais OFDM. Isto significa que o esquema de medição de erro vetorial proposto permite definir a precisão da modulação de transmissão e assim garantir a interoperabilidade entre terminais sem fio.

Abstract: This paper proposes a new vector error measurement scheme for orthogonal frequency division multiplexing (OFDM) systems that is used to define transmit modulation accuracy. The transmit modulation accuracy is defined to guarantee inter-operability among wireless terminals. In OFDM systems, the transmit modulation accuracy measured by the conventional vector error measurement scheme can not guarantee inter-operability due to the effect of phase noise. To overcome this problem, the proposed vector error measurement scheme utilizes pilot signals in multiple OFDM symbols to compensate the phase rotation caused by the phase noise. Computer simulation results show that the vector error measured by the proposed scheme uniquely corresponds to the C/N degradation in packet error rate even if phase noise exists in the OFDM signals. This means that the proposed vector error measurement scheme makes it possible to define the transmit modulation accuracy and so guarantee inter-operability among wireless terminals.
