System and method for controlling peak to average power ratio

A method for reducing peak to average power ratio in a wireless communication system, comprising:

• detecting amplitude values in a signal to be transmitted that exceed a predetermined amplitude;
• inverting a bit of a symbol that is identified as causing the amplitude of the signal to exceed the predetermined amplitude;
• and
• selecting the bit to invert such that:
• inversion of the bit reduces the amplitude of the signal;
• and
• forward error correction in a receiver wirelessly coupled to the transmitter that inverts the bit restores the bit to a pre-inversion value.

A transmitter for a wireless backhaul system, comprising:

• signal peak reduction circuitry configured to reduce peak to average power ratio of
• a signal to be transmitted by reducing amplitude of the signal to be transmitted that is greater than a predetermined amplitude, the signal peak reduction circuitry comprising:
• an interpolator configured to generate a representation of the signal to be transmitted based on the symbols to which data to be transmitted is mapped;
• a peak detector configured to detect, based on the representation of the signal, amplitude values in the signal to be transmitted that exceed the predetermined amplitude;
• and
• a bit inverter configured to:
• invert a bit of a symbol identified as causing the amplitude of the signal to exceed the predetermined amplitude;
• and
• select the bit to invert such that:
• inversion of the bit reduces the amplitude of transmitted signal;
• and
• forward error correction in a receiver wirelessly coupled to the transmitter restores the inverted bit to a pre-inversion value.
