Disclosed is a receiver transmitter architecture having incorporated both open loop transmit diversity schemes using a plurality of binary switches. Employment of binary switches allows for the sharing of certain components whether the receiver is utilizing a orthogonal transmit diversity (OTD) scheme or a space time spreading (STS) scheme. Accordingly, the number of components in the receiver is minimized and the complexity of the receiver is simple enough to be implemented into a single application specific integrated chip. IMAGE
