Patent ID: 7852811

Claim:
A wireless communication method for a multiple input, multiple output (MIMO) system that includes MIMO channel estimation using peak-limited pilot signals, the method comprising: receiving a transmitted, peak-limited pilot signal on m multiple antennas of a receiver, wherein “m” is an integer greater than one (1) and the transmitted, peak-limited pilot signal is based on a first pilot signal, and wherein receiving the transmitted, peak-limited pilot signal further comprises receiving signal r, where signal r is a vector and r =H y p (n)′+η, H is a matrix representing a MIMO channel, y p (n)′ is a vector representing the peak-limited version of the first pilot signal, and η is a vector representing noise; and determining an estimated MIMO channel from the received peak-limited pilot signal using a synthesized, peak-limited version of the first pilot signal, wherein the synthesized, peak-limited version of the first pilot signal is synthesized at the receiver.
