| 4. An apparatus for receiving signals through a plurality of antennas in a mobile communication system that inputs a sequence
of coding bits and outputs information bits, the apparatus comprising:
despreaders for despreading each sequence of modulation symbols received through the plurality of antennas by a despreading
code identical to the despreading code used in a transmission apparatus;
a mean minimum square error (MMSE) receiver for detecting an error component for the despread modulation symbols; and
an error detector for selecting modulation symbols having an error component higher than a preset value and estimating a transmission
symbol for the selected modulation symbols.
