Abstract
A method and an apparatus for implementing transmission diversity using a single transmitter in a wireless communication system are provided. The method of operating a transmitter for transmission diversity in a wireless communication system includes generating a first data symbol by receiving a baseband signal from a data source, generating a second data symbol having an equal phase to the first data symbol, generating a first complex conjugate symbol by performing a complex conjugate operation for the first data symbol, generating a second complex conjugate symbol having a phase difference of 180 degrees from the first complex conjugate symbol, transmitting the first data symbol through a first transmission antenna and transmitting the second data symbol through a second transmission antenna in a first time slot, and transmitting the first complex conjugate symbol through the first transmission antenna and transmitting the second complex conjugate symbol through the second transmission antenna in a second time slot.
