Abstract
A system, wireless device () and method reduce the peak-to-average power of a transmitter by creating at least two sampled carrier data streams, running each carrier through a separate delay block, mixing each carrier over in frequency an appropriate amount, resulting in at least two frequency division multiplexed signals, and combining the at least two frequency division multiplexed signals together. The four sampled carrier data streams may each have a bandwidth of 25 kHz. Each separate delay block is less than 20% of its corresponding symbol time. The transmitter may be used to transmit wideband integrated digitally enhanced network (WiDEN) signals.
