1. 1. Performance evaluation of interleaving techniques for IEEE 802.15.4 transmissions

   University essay from Mittuniversitetet/Avdelningen för informations- och kommunikationssystem

   Author : Jiahuan Lei; Qingbi Liao; [2014]
   Keywords : interleaving; Matlab; Reed-Solomon; TinyOS; WSN; FEC; MicaZ;

   Abstract : In the wireless sensor network, the WLAN interference, multi-path fading andattenuation are the main reason for packets’ corruption. Forward errorcorrection is one of the methods for error mitigation. Many coding methods aredesigned to improve the reliability of wireless channel. READ MORE

4. 3. Analysis of OSTBC in Cooperative Cognitive Radio Networks using 2-hop DF Relaying Protocol

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : Muhammad Mustafa Tahseen; MatiUllah Khan; Farhan Ullah; [2011]
   Keywords : Cognitive Radio; Cooperative Communication; Alamouti STBC; OSTBC; Rayleigh Fading; Energy Detector; DF Relay; Maximum Likelihood; MRC;

   Abstract : To achieve cooperative diversity in cognitive radio network, Decode and Forward (DF) protocol is implemented at Cognitive Radios (CRs) using Orthogonal Space Time Block Coding (OSTBC). The 2-hop communication between source and destination is completed with the help of Cognitive Relays (CRs) using Multiple Input Multiple Output (MIMO) technology within the network. READ MORE

5. 4. PERFORMANCE ANALYSIS ON MODULATION TECHNIQUES OF W-CDMA IN MULTIPATH FADING CHANNEL

   University essay from Blekinge Tekniska Högskola/Avdelningen för signalbehandling

   Author : AUN ALI TAHIR; FENG ZHAO; [2009]
   Keywords : Final Thesis as Part for Master program in Electrical Engineering with Emphasis on Telecommunication;

   Abstract : The transmission from base station to mobile or downlink transmission using M-ary Quadrature Amplitude modulation (QAM) and Quadrature phase shift keying (QPSK) modulation scheme are consider in W-CDMA system. We can analysis the performance of these modulation techniques when the system is subjected to AWGN and multipath Rayleigh fading are consider in the channel. READ MORE

6. 5. Channel Estimation in GPRS based Communication System using Bayesian Demodulation.

   University essay from Blekinge Tekniska Högskola/Avdelningen för telekommunikationssystem
