Abstract
The present invention relates to a transmitting apparatus using a spread-spectrum transmission scheme. The transmitting apparatus includes a precoder for preceding a data signal by performing a product operation between a first matrix and a diagonal matrix. The preceding 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.
Claims5
A transmitting apparatus that employs a spread-spectrum transmission scheme, the transmitting apparatus comprising a precoder for precoding a transmit data signal by using a first matrix and a diagonal matrix and generating an output signal of the preceding, the first matrix including one of a discrete cosine transform (DCT) matrix, a discrete Hartley transform (DHT) matrix, and a discrete sine transform (DST) matrix.
