Os sistemas de comunicação por multiplexação por divisão ortogonal de frequência (OFDM) apresentam grandes vantagens, como alta eficiência de espectro e robustez contra o desvanecimento por múltiplos caminhos. A fim de aumentar as vantagens, este artigo investiga uma utilização eficiente tanto da combinação de diversidade quanto da modulação de nível superior (modulação adaptativa) com um código de repetição no domínio da frequência nos sistemas OFDM. Os sistemas OFDM codificados por repetição podem alcançar uma melhoria de desempenho com uma estrutura tão simples como um par de antenas de transmissão/recepção. Neste artigo, derivamos equações simples de forma fechada para probabilidade de erro de bit (BEP) e taxa de transferência, e então as melhorias desses desempenhos nos sistemas OFDM propostos são verificadas tanto pela análise teórica quanto pela simulação de Monte Carlo.

Abstract: Orthogonal frequency division multiplexing (OFDM) communication systems have great advantages, such as high spectrum efficiency and robustness against multipath fading. In order to enhance the advantages, this paper investigates an efficient utilization of both diversity combining and higher-level modulation (adaptive modulation) with a repetition code on the frequency domain in the OFDM systems. The repetition coded OFDM systems can achieve an improvement of performance with such a simple structure as one pair of transmit/receive antennas. In this paper, we derive simple closed-form equations for bit error probability (BEP) and throughput, and then improvements of those performances in the proposed OFDM systems are verified by both theoretical analysis and Monte Carlo simulation.
