Wireless transceiver and wireless transmitting/receiving method and program thereof

Image Number 3 for United States Patent #8090039.

The present invention is provided with a wireless transceiver and wireless transmitting/receiving method and program thereof capable of improving the robustness against Doppler frequency by containing transmit diversity signals in one spreading region. In the present invention, the transmitter encodes the transmit signals using a space-time matrix and transmits the encoded space-time signals after being spread with different spreading codes, and the receiver de-spreads the received spread signals, in unit of time slot, with the spreading codes corresponding to the respective time slots and then decodes the de-spread signals using the space-time matrix.
