ABSTRACT:
The present invention is directed to apparatus and method for encoding and decoding data within a wireless network such that a MS preferably does not require multiple receivers to handle communications from BTSs with varying numbers of antennas. In embodiments of the present invention, a space-time matrix is utilized to encode the data streams being transmitted from a BTS such that a BTS with fewer antennas would simply have an encoding matrix with one or more of the columns or rows removed from the matrix. In this way, the MSs within the wireless network can be designed to decode with the use of only a single space-time encoding matrix, this space-time encoding matrix working for BTSs with various numbers of antennas.
