متن کاملMulticarrier Digital Pre-distortion/ Equalization Techniques for Non-linear Satellite Channels
Two key advances are envisaged for future missions: (a) spectrally efficient transmission to meet the increasing demand and (b) sharing of satellite capacity among different links to meet power/mass requirements. Joint amplification of multiple-carrier DVB-S2 signals using a single High-Power Amplifier (HPA) is a particular application of satellite resource sharing. However, effects specific to...
متن کاملDiversity Order of Infinite-length Symbol-by-symbol Linear Equalization
The processing complexity of optimal receivers in frequency selective channels grows exponentially with the channel memory length. Linear receivers, alternatively, offer significantly less complexity with the cost of performance degradation. Such degradation can be due to not fully capturing the inherent frequency diversity or degraded coding gain. In this paper we investigate how effectively t...
متن کاملMultistage Symbol-by-symbol Bayesian Interference Cancellation for Umts-cdma Links Affected by Severe Multipath
A simple multiuser detector (MUD) is proposed for UMTSCDMA links over channels affected by severe multipath. After coherent combining and despreading, for each user a suitable “Bayesian” memoryless non-linearity gives symbolby-symbol the expected values of the transmitted data. These are employed for soft removal of inter-symbol and multipleaccess interference from the received sequences. The p...
متن کاملInterference cancellation and blind equalization for linear multi-user systems
Potential applications of blind channel identi cation and equalization in wireless communication systems have been recently explored. For multi-user systems that are irreducible and column-reduced, second order statistical methods normally can identify channel dynamics up to a unitary mixing matrix. In this paper, we investigate the equalizability of desired users and the cancellation of unwant...
