... relays and in the second one the relays forward that information to the UT using the QO- SFBC. The difference in having two antennas at the RNs instead of one is in the modulation used, since ... By replacing the modulation factor gain and after some simplifications, we get the final expression for the gain obtained when using the precoded algorithm instead of the DCA o...
