Rolling code — A rolling code (or sometimes called a hopping code) is used in keyless entry systems to prevent replay attacks (Where an eavesdropper records the transmission and replays it at a latertime to cause the receiver to unlock .)Such systems are… … Wikipedia
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. A spread spectrum transmission offers three main advantages over… … Wikipedia
Frequency Hopping — Mit Frequenzspreizung bezeichnet man in der Informationsübertragung per Funk ein Verfahren, bei dem ein schmalbandiges Signal in ein Signal mit einer größeren Bandbreite als für die Informationsübertragung nötig umgewandelt wird. Die Sendeenergie … Deutsch Wikipedia
Multi-carrier code division multiple access — (MC CDMA) is a multiple access scheme used in OFDM based telecommunication systems, allowing the system to support multiple users at the same time. MC CDMA spreads each user symbol in the frequency domain. That is, each user symbol is carried… … Wikipedia
