Abstract:
1. A transmitting apparatus of a multi-carrier system using multiple antennas comprising: a linear complex field (LCF) encoder for performing a linear precoding to input signals to be transmitted to a receiving apparatus using a linear complex matrix considering the number of multiple antennas and the number of subcarriers; a subcarrier allocator for respectively allocating a subcarrier to the signals linear-precoded by the LCF encoder; and, a transmitter for respectively transmitting the signals having a subcarrier allocated by the subcarrier allocator through the multiple antennas externally, wherein the linear complex matrix has a row and column corresponding to a product mn of the number m of multiple antennas and the number n of subcarriers, and the LCF encoder performs a precoding to the input signals corresponding to the product mn using the linear complex matrix as follows: wherein, U x a
