Abstract  Abstract

The invention supplies the transmission and the reception of data signal using multi transmission antenna. Each antenna transmission has the different guiding frequency signal of pseudo random chip code sequence. A receiver filters each transmitted guiding frequency signal by using the chip code of guiding frequency signal. The filtered guiding frequency is weighted and combined. The weighting number of each guiding frequency has a part on the signal quality of the combined signal properly adjusted. A data signal is transmitted to make the different spreading spectrum version of data signal transmitted from each antenna. Each version has different chip recognizer version. Each version is filtered by the relation chip code during receiving. The filtered version according to guiding signal received by the antenna in relation to adjusted weight is weighted.
