Description: echniques for multi-user detection in OFDM / MC-CDMA can be classified as linear or non-linear techniques. A number of these techniques have evolved from previous research for CDMA–based systems. The overlaying of OFDM with CDMA permits grouping of the received signals based on received power, and this fact is exploited by the techniques discussed below. This project is going to focus on some of the more recent advances in some of the non-linear multi-user detection (MUD) techniques. A brief summary of the various techniques are given below. (Maximum Likelihood detection is not discussed here because of the computation complexity involved.)-echniques for multi-user detection in OFDM/MC-CDMA can be classified as linear or non-linear techniques.

Description: This paper studied the carrier-frequency offset effect on the performance of asynchronous multicarrier direct-sequence code-division multiple-access (MC-DS-CDMA) systems with aperiodic random spreading and correlated Rayleigh fading. This paper also compared the performance of MC-CDMA systems using the optimum combining technique with that of different combining filters.

Description: 一篇非常实用的无线通信方向的文献，是关于cdma系统中doa估计的经典-The use of antenna arrays in wireless communications
makes it possible to estimate the directions of arrival (DOAs)
of impinging waveforms. The latter can be exploited to enhance
channel estimation accuracy or as an input for advanced mobile
positioning systems. In this paper, we consider the uplink of a
multicarrier code-division multiple-access (MC-CDMA) network
in which the base station is endowed with multiple receiving antennas
arranged in a uniform linear array. Transmission takes place
over a multipath channel, and the goal is the joint estimation of
the channel responses and DOAs of the uplink signals. In doing so,
we follow a maximum-likelihood (ML) approach and assume that
users transmit orthogonal training sequences to facilitate the task
of separating the signals. This way, all unknown parameters are
estimated independently of each other with affordable complexity.
Theoretical analysis and computer simulations are used to assess
the performance of the propose

Description: In this paper, we investigate blind channel estimation for Multiple Input Multiple Output (MIMO) multi-carrier
CDMA (MC-CDMA) systems in the uplink scenario. An Autocorrelation Contribution Matrix (ACM) method is proposed in
comparison with the subspace approach. Using only second order
statistics, the ACM approach shows similar performance to that
of subspace based approach. The added advantage is that it eliminates the need for rank estimation and noise power calculation
as in subspace technique. In particular we incorporate blind
channel estimation with Layered Space Frequency Equalisation
(LSFE),which employs successive interference cancellation and
therefore provides significant performance improvement over the
conventional linear minimum mean square error (MMSE) based
approach.
