1. 1. M-PSK and M-QAM Modulation/Demodulation of UWB Signal Using Six-Port Correlator

   Master-uppsats, Fysik och elektroteknik

   Författare :Negar A. Sani; [2010]
   Nyckelord :Six-Port Correlator; Ultra Wideband; Wireless Communication; Modulation; Demodulation; M-QAM; M-PSK;

   Sammanfattning : Nowadays high speed and high data rate communication are highly demanded. Consequently, wideband and high frequency transmitter and receivers should be designed. New transmitters and receivers should also have low power consumption, simple design and low manufacturing price in order to fulfill manufacturers’ requests for mass production. LÄS MER

3. 2. Efficient Message Passing Decoding Using Vector-based Messages

   Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

   Författare :Mikael Grimnell; Mats Tjäder; [2005]
   Nyckelord :Forward Error Correction; Low Density Parity Check Codes; Message Passing Decoding; Belief Propagation; Extrinsic Information Transfer; Galois Fields; Phase Shift Keying;

   Sammanfattning : The family of Low Density Parity Check (LDPC) codes is a strong candidate to be used as Forward Error Correction (FEC) in future communication systems due to its strong error correction capability. Most LDPC decoders use the Message Passing algorithm for decoding, which is an iterative algorithm that passes messages between its variable nodes and check nodes. LÄS MER
