| Abstract(in English) | This paper investigates the impact of quantization error to the bit error rate performance of a COFDM receiver employing the pre-DFT combining space diversity. Although the pre-DFT combining space diversity is an efficient technique capable of reducing the computational cost of the space diversity, it is expected to require more accurate quantization, since the dinamic range of pre-DFT at the input of the DFT processor is wider than that of the conventional post-DFT one. Computer simulation results show that the growth in the number of quantization bits is only one bit even if the eight-branch diversity was employed. |
