| 1. A method of transmitting data in a wireless communication system from a transmitter to a receiver, the method comprising:
modulating data at the transmitter using a first 16-QAM modulation scheme to obtain a first 16-QAM data symbol;
transmitting the first data symbol to the receiver over a first diversity branch;
modulating said data at the transmitter using a second 16-QAM modulation scheme to obtain a second 16-QAM data symbol; and
transmitting the second 16-QAM data symbol to the receiver over a second diversity branch, wherein:
first and second constellation bit mappings defining the first and second 16-QAM modulation schemes are different.
