27. Error Rate Performance of Multi-Hop Communication Systems Over Nakagami-m Fading Channel
University essay from Institutionen för datavetenskap, fysik och matematik, DFMAbstract : 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.

29. Estimating the frequency response of a receiver : Blind identification
University essay from Akademin för teknik och miljöAbstract : Consider a receiver that has an unknown impulse response in the form of linear time-invariant system, which is driven by an input signal and random noise with an unknown distribution. If the unknown impulse response of the receiver could be identified, then its equivalent frequency response can be used for calibration, using deconvolution aiming to regain the original signal under measurement.

30. Impact of Interference from Primary User on the Performance of Cognitive Radio Networks
University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskapAbstract : This thesis report presents background knowledge about cognitive radio network (CRN) and investigates performance of underlay cognitive radio networks based on an adaptive power allocation policy of secondary transmitter (SU-Tx). In particular, it has been assumed that SU-Tx and primary user transmitter (PU-Tx) are equipped with a single antenna, while the corresponding receivers are equipped with multiple antennas. READ MORE
