Em sistemas MIMO, a implantação de uma técnica de múltiplas antenas pode melhorar o desempenho do sistema. Porém, como o custo dos transmissores de RF é muito superior ao das antenas, há um interesse crescente em técnicas que utilizam um número maior de antenas do que o número de transmissores de RF. Esses métodos dependem da seleção das antenas transmissoras ideais e da conexão delas às respectivas. Neste caso, as informações de feedback (FBI) são necessárias para selecionar os elementos ideais da antena do transmissor. Como o FBI é uma sobrecarga de controle, a taxa de feedback é limitada. Isto motiva o estudo de técnicas de feedback limitadas, onde apenas informações parciais ou quantizadas do receptor são transmitidas de volta ao transmissor. No entanto, em sistemas MIMO/OFDM, é difícil desenvolver um método de quantização FBI eficaz para escolher o processamento de espaço-tempo, espaço-frequência ou espaço-tempo-frequência devido aos numerosos subcanais. Além disso, os sistemas MIMO/OFDM requerem uma separação de antena de 5

Abstract: In MIMO systems, the deployment of a multiple antenna technique can enhance the system performance. However, since the cost of RF transmitters is much higher than that of antennas, there is growing interest in techniques that use a larger number of antennas than the number of RF transmitters. These methods rely on selecting the optimal transmitter antennas and connecting them to the respective. In this case, feedback information (FBI) is required to select the optimal transmitter antenna elements. Since FBI is control overhead, the rate of the feedback is limited. This motivates the study of limited feedback techniques where only partial or quantized information from the receiver is conveyed back to the transmitter. However, in MIMO/OFDM systems, it is difficult to develop an effective FBI quantization method for choosing the space-time, space-frequency, or space-time-frequency processing due to the numerous subchannels. Moreover, MIMO/OFDM systems require antenna separation of 5
