• Orthogonal frequency-division multiplexing [OFDM]
  
• Phase-shift keying [PSK]
  

• Direct-sequence spread spectrum [DSSS]
  

  In telecommunications, direct-sequence spread spectrum (DSSS) is a modulation technique. As with other spread spectrum technologies, the transmitted signal takes up more bandwidth than the information signal that is being modulated. The name 'spread spectrum' comes from the fact that the carrier signals occur over the full bandwidth (spectrum) of a device's transmitting frequency.

  • Used in:

  The United States GPS and European Galileo satellite navigation systems

  CDMA cellular phones

  Cordless phones operating in the 2.4 and 5.8 GHz bands

  802.11 and 802.11b Wi-Fi standards (The faster modes in 802.11g use OFDM, not spread spectrum, although it can fall back to the slower 802.11b modes)

  ZigBee / 802.15.4

  From: http://en.wikipedia.org/wiki/Direct-sequence_spread_spectrum

• Frequency-hopping spread spectrum [FHSS]
  

  Frequency-hopping spread spectrum (FHSS) is a method of transmitting radio signals by rapidly switching a carrier among many frequency channels, using a pseudorandom sequence known to both transmitter and receiver.

  The most celebrated invention of frequency hopping was that of actress Hedy Lamarr and composer George Antheil, who in 1942 received patent number 2,292,387 for their "Secret Communications System."
