Abstract:
A wireless communication apparatus and method minimizes degradation in a separation characteristic of a code-multiplexed response signal using two-dimensional processing. One of plural cyclic shift values defines a reference signal sequence that is spread with an orthogonal sequence associated with one of the plural cyclic shift values. This two-dimensional processing compensates for interference affecting the reference signal.
