Performance evaluation of cooperative communications for stfc mb-ofdm uwb abstract recently, the combination of cooperative communication, space-time-frequency codes (stfcs) and. Cooperative ofdm relay network performs similarly to cooperative sc-fde relay network in a frequency-selective fading channel keywords: cooperative relaying, sc-fde, ofdm, channel estimation, mmse introduction wireless channel is characterized by multipath propagation environments which causes an inter-symbol interference (isi. With cooperative ofdm/tdm in comparison with ofdm based cooperative network, since cooperative ofdm/tdm network exploits both frequency and cooperative diversity gains the remainder of this paper is organized as follows sec-tion ii presents the network model performance analysis in sect iii in sect iv, numerical results and discussions are presented.
Abstract: cooperative networking schemes provide spatial diversity gain (named cooperative diversity gain) using the antennas of spatially distributed users consistent research has been focusing on cooperative networks using orthogonal frequency division multiplexing (ofdm) and single carrier with. Frequency division multiplexing (ofdm) can provide high data rate and better performance and a combination of ofdm and cooperative communication may push a wireless network forward to its next generation with enhanced reliability and efficiency.
In this paper, we investigate the diversity, capacity and complexity issues of cooperative zero-padding (zp)-orthogonal frequency division multiplexing (ofdm) communication we consider cooperative zp-ofdm communication over a multipath rayleigh channel and with multiple carrier frequency offsets (cfos) existing at different relays. Cooperative communications is a new communication paradigm which generates independent paths between the user and the base station by introducing a relay channel. On performance of cooperative ofdm/tdm with frequency-domain equalization in a multipath wireless channel abstract: cooperative transmission, where spatially distributed users form a multi-antenna system and assist in forwarding the information from source to destination node, achieves the diversity gain of a multiple-input multiple-output.
Cooperative network based on ofdm has been proposed to cope with the channel frequency-selectivity but due to high peak-to-average power ratio (papr) of ofdm, expensive power amplifier are required.
