Patent ID: 8335274

Claim:
A method of spatially precoding data in a channel independent way, said method comprising the steps of: selecting a transmission rank based on a transmission rank of a communication channel; selecting a set of one or more precoding filters derived from a single generator matrix based on said transmission rank, wherein selecting the set of precoding filters comprises selecting one or more columns of the single generator matrix for each precoding filter, and wherein the number of columns selected for each precoding filter equals the selected transmission rank; and precoding data for transmission to a remote device using said precoding filters in a predetermined order according to a predetermined precoding sequence, thus using different ones of said precoding filters during different precoding intervals in a precoding period of the predetermined precoding sequence, wherein selecting the set of precoding filters further comprises selecting the set of precoding filters such that each column of the generator matrix is used a same number of times during the predetermined precoding sequence.
