Abstract

The disclosed embodiments provide for methods and systems for transmitting a number of streams of modulation symbols by a multi-antenna transmitter. In one aspect, a method for transmitting a number of streams of modulation symbols by a multi-antenna transmitter includes the acts of transforming a first number of streams of symbols to a second number of streams of symbols, the first number being smaller than or to the second number; and transmitting the second number of streams of symbols by a transmitter having the second number of antennas.
