Abstract  Abstract

The invention claims a transmission and receiving of data signals from a plurality of transmission antennas. Each antenna transmits a different pilot signal having a pseudo random chip code sequence. A receiver filters each using the chip code of the pilot signal of the transmitted pilot signal. the filtered pilots are weighted and combined. a part on the signal quality of the combined signal is properly adjusted weights for each pilot signal. A data signal is transmitted such that different spread frequency versions of the data signal are transmitted from each antenna. version of each version having a different chip code identifier. in reception each version is filtered with its associated chip code. the filtered according to a version of the pilot signal by the receiving antenna associated adjusted weight is weighted.

The invention provides for transmission and reception of a data signal using a plurality of transmitting antennas. Each antenna transmits a different pilot signal having a pseudo random chip code sequence. A receiver filters each transmitted pilot using that pilots chip code. The filtered pilots are weighted and combined. Each pilot signals weight is adaptively adjusted in part on a signal quality of the combined signal. A data signal is transmitted such that different spread spectrum versions of the data signal are transmitted from each transmitting antenna. Each version having a different chip code identifier. Upon reception each version is filtered with its associated chip code. The filtered versions are weighted in accordance with the adjusted weights associated with the pilot signal of the respective antenna.
