Performance of MHPM in Rician and Rayleigh fading mobile channels
This paper evaluates the error probability of the rectangular frequency pulse multi-h modulation (MHPM) scheme in slowly-fading, frequency-nonselective or frequency-selective Rician and Rayleigh channels. The evaluation is performed with a method combining analysis and computer simulation. Performance degradations are evaluated for various direct-to-reflected signal ratio, Doppler shifts, and r...
متن کاملAn Upper Bound of Soft Decode and Forward Relaying Over Rayleigh Fading Channels
In this paper, we investigate a distributed turbo code (DTC) scheme dedicated to L-relay channels operating in the soft-decode-and-forward (soft-DF) mode. At the destination, the received replicas are combined using the maximal ratio combining (MRC). Then, we define the explicit upper bound for error rate assuming Binary phase shift keying (BPSK) transmission for fully interleaved channels with...
متن کاملDistributed Space-Time Block Code over Mixed Rayleigh and Rician Frequency-Selective Fading Channels
This paper proposes a new distributed space-time block code (DSTBC) over frequency-selective fading channels for two-hop amplify and forward relay networks, consisting of a source node (S), two relay nodes (R1 and R2), and a destination node (D). The proposed DSTBC is designed to achieve maximal spatial diversity gain and decoupling detection of data blocks with a lowcomplexity receiver. To ach...
متن کاملAdaptive Modulation in Coded Cooperation under Rayleigh Fading Channels
Cooperative communication provides a new way of introducing spatial diversity to wireless systems. In order to increase the spectral efficiency of coded cooperative relaying system, the adaptive modulation technique is presented under Rayleigh fading channel in this paper. The source and relay adapt their modulation schemes based on the channel condition of all three links, i.e. source to relay...
متن کاملPerformance Analysis of OFDM-Based Decode-and-Forward Relay Network with Multiple Interferers over Rayleigh Fading Channels
Relay communications, as a promising technique to help in attaining broader coverage and combating the impairments of the wireless channel, have gained significant interests at the beginning of this century [1–3]. Recently, various cooperation protocols, for example, amplify-and-forward (AF) and decode-and-forward (DF) [2], have been proposed for cooperative wireless networks. Subsequently, the...
