Abstract
Precoding for multiple transmission streams in multiple antenna systems. Embodiments herein disclose a general method that transmits signal from multiple antennas using a one/two dimensional precoder followed by STBC/SFBC or SM encoder. This precoder is fixed in a given resource block (RB) or slot, which is composed of P subcarriers and Q OFDM symbols (where the values for P and Q are greater than or 5 equal to 1). The precoder in each resource block may take same or different values, which span the two dimensional time-frequency grid. The precoder is chosen as a function of either logical frequency index or physical frequency index of the RB.
