Abstract

The present invention relates to a transmitting apparatus using a spread-spectrum transmission scheme. The transmitting apparatus includes a precoder for precoding a data signal by performing a product operation between a first matrix and a diagonal matrix. The precoding outputs a signal responding to the input data by performing a product operation between the first matrix and the diagonal matrix. Such a transmitting apparatus obtains a maximum diversity gain.
