We analyze the total ergodic spectral efficiency and sum-rates error-exponents of randomly-spread CDMA systems with diversity-combining linear multiuser receivers over time-varying frequency-selective multipath Rayleigh/Ricean fading channels. The basis of our analysis mainly being the joint/average eigenvalue density of the random cross-correlation matrices, our focus is on equal-rate/equal-energy identical users with statistically i.i.d. channels. The upper-bound ergodic spectral efficiency and the corresponding sum-rates error-exponent expressions are derived in closed-form in terms of the key system parameters for linear multiuser receivers with single-user ML decoding. The analysis sheds light onto asymptotic behaviour of channel-coded wideband CDMA systems over multipath fading channels.

Total outage capacity of randomly-spread coded-CDMA with linear multiuser receivers over multipath fading channels Ertug, O; Sayrac, B; Baykal, Buyurman; Yucel, MD (2003-07-03) We address in this paper the derivation and analysis of the outage spectral efficiencies achievable with linear multiuser receivers over randomly-spread multipath fading time-varying coded-CDMA channels. The basis of the derivations is the use of non-asymptotic average eigenvalue densities of random cross-correlation matrices. The analysis give important clues on the achievable capacity with linear multiuser receivers under non-ergodic transmission situations.
Approximate Bayesian Smoothing with Unknown Process and Measurement Noise Covariances Ardeshiri, Tohid; Özkan, Emre; Orguner, Umut; Gustafsson, Fredrik (2015-12-01) We present an adaptive smoother for linear state-space models with unknown process and measurement noise covariances. The proposed method utilizes the variational Bayes technique to perform approximate inference. The resulting smoother is computationally efficient, easy to implement, and can be applied to high dimensional linear systems. The performance of the algorithm is illustrated on a target tracking example.
Out-of-band radiation and CFO immunity of potential 5G multicarrier modulation schemes Üçüncü, Ali Bulut; Yılmaz, Ali Özgür; Department of Electrical and Electronics Engineering (2015) In this study, generalized frequency division multiplexing (GFDM) and windowed cyclic preﬁx circular offset quadrature amplitude modulation (WCP-COQAM), which are candidate physical layer modulation schemes for the 5G systems, are compared to orthogonal frequency division multiplexing (OFDM) in terms of out-of-band (OOB) radiation levels and carrier frequency offset (CFO) immunity. GFDM and WCP- COQAM are shown to be superior to OFDM with respect to OOB emissions in some studies in literature. However, we c...
Methodology for performance analysis of randomly-spread CDMA systems over multipath fading channels via crosscorrelation matrix non-asymptotic average eigenvalue densities Ertug, O; Baykal, Buyurman; Unal, BS (Institution of Engineering and Technology (IET), 2003-08-07) A new methodology for closed-form theoretical performance analysis of randomly-spread CDMA systems over multipath fading channels with multiuser receivers is presented. The basis of the analysis is the representation of the random signal to interference ratios at finite system parameters in terms of the eigenvalues of crosscorrelation matrices for which the non-asymptotic average densities are found or known, The methodology presented complements the asymptotic Ruining theory used in similar previous work o...
An Efficient Hybrid Beamforming and Channel Acquisition for Wideband mm-Wave Massive MIMO Channels Kurt, Anıl; Güvensen, Gökhan Muzaffer (2019-01-01) In this paper, an efficient hybrid beamforming architecture together with a novel spatio-temporal receiver processing is proposed for single-carrier (SC) mm-wave wideband massive MIMO channels in time-domain duplex (TDD) mode. The design of two-stage beamformers is realized by using a virtual sectorization via second-order channel statistics based user grouping. The novel feature of the proposed architecture is that the effect of both inter-group-interference (due to non-orthogonality of virtual angular sec...
