1. 6. Comparison and Evaluation of Doppler Spread Estimation Algorithms in WCDMA

   University essay from KTH/Kommunikationsteori

   Author : Hui Wen; [2014]
   Keywords : ;

   Abstract : In a WCDMA transmission systems, the properties of the radio transmissionchannels can be strongly aected by the movement of User Equipment (UE) orthe surrounding objects. The estimation of Doppler spread is therefore of greatimportance since it is closely related to the mobile speed, as it can also be usedto characterize the fast fading in the radio channel.

3. 7. Performance and Complexity Comparison of Doppler Spread Estimation for WCDMA Systems

   University essay from KTH/Kommunikationsteori

   Author : Ziqi Peng; [2014]
   Keywords : Doppler spread estimation; WCDMA uplink systems; Rayleigh fading model; Rician fading model; computational complexity.;

   Abstract : In cellular communication systems, the estimation of Doppler spread has a wide range of applications such as handoff, channel assignment scheme, adaptivetransmission, power control, etc. A great quantity of Doppler spread estimation algorithms have been proposed in the literature.

4. 8. Performance of MLSE over Fading Channels

   University essay from Institutionen för fysik och elektroteknik (IFE)

   Author : Aftab Ahmad; [2013]
   Keywords : ;

   Abstract : This work examines the performance of a wireless transceiver system. The environment is indoor channelsimulated by Rayleigh and Rician fading channels. The modulation scheme implemented is GMSK inthe transmitter. In the receiver the Viterbi MLSE is implemented to cancel noise and interference dueto the ltering and the channel. READ MORE

5. 9. Error Rate Performance of Multi-Hop Communication Systems Over Nakagami-m Fading Channel

   University essay from Institutionen för datavetenskap, fysik och matematik, DFM

   Author : Hassan Sajjad; Muhammad Jamil; [2012]
   Keywords : Signal Processing; Fading Channel; Multi-hop;

   Abstract : This work examines error rate performance of Multi-Hop communication systems, employing Single Input Single Output (SISO) transmissions over Nakagami-m fading channel. Mobile multi-hop relaying (MMR) system has been adopted in several Broadband Wireless Access Networks (BWAN) as a cost-effective means of extending the coverage and improving the capacity of these wireless networks.

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

   University essay from Blekinge Tekniska Högskola/Avdelningen för telekommunikationssystem

   Author : Dileep Kumar Appana; Chinni Anil Kumar; Nagappan Palaniappan Nagappan; [2009]
   Keywords : Bayesian; techniques; demodulation; demodulator; GPRS; rayleigh; fading; channel; dileep; appana; chinni; anil; nagappan; palaniappan; blekinge; tekniska; högskolan; institue; technology; master; thesis;

   Abstract : With the increase use of portable devices such as Personal Digital Assistants (PDA), laptops, voice and data integrated cell phones and many more, there is a need of wireless communication method using air as the medium to transmit and receive information between terminals. Radio waves propagate from transmitting antenna and travel through free space undergoing reflections, diffractions and scattering. READ MORE
