Apparatus and method for transmitting and receiving signal in multi-antenna communication system

摘要

Provided is a method and apparatus for transmitting and receiving a signal in a multi-antenna communication system. A method of transmitting a signal via a multipath channel in the multi-antenna communication system may include: generating continuous orthogonal spreading codes; spread-modulating a user signal using the continuous orthogonal spreading codes to generate a spread signal; performing pre-rake combining of the spread signal to generate a pre-rake synthesized signal; and transmitting the pre-rake synthesized signal via multiple antennas.
