The performance of a near-far-resistant, finite-complexity, minimum mean squared error (MMSE) linear detector for demodulating direct sequence (DS) code-division multiple access (CDMA) signals is studied, assuming that the users are assigned random signature sequences. We obtain tight upper and lower bounds on the expected near-far resistance of the MMSE detector, averaged over signature sequences and delays, as a function of the processing gain and the number of users. Since the MMSE detector…

Asynchronous CDMA Systems With Random Spreading—Part I: Fundamental Limits

TLDR
Spectral efficiency for asynchronous code division multiple access (CDMA) with random spreading is calculated in the large system limit allowing for arbitrary chip waveforms and frequency-flat fading and the analysis of linear MMSE detectors shows that the limiting interference effects can be decoupled both in the user domain and in the frequency domain such that the concept of effective interference spectral density arises.

Optimum near-far resistance for dual-rate DS/CDMA signals: Random signature sequence analysis

TLDR
The results for the VSL scheme with general random codes are extended for performance evaluation of systems with signature sequences which span many symbol intervals, showing that the performance depends on the access schemes and the data rate of the users.

Optimum asymptotic multiuser efficiency of randomly spread CDMA

TLDR
This correspondence analyzes the high signal-to-noise ratio (SNR) performance of optimum multiuser detectors for synchronous direct-sequence spread spectrum with random spreading in an additive white Gaussian noise channel and shows that the optimum asymptotic efficiency of a K-user system with spreading gain N converges to 1 almost surely as K/spl rarr//spl infin.

Large-system performance analysis of blind and group-blind multiuser receivers

TLDR
The results reveal an interesting "saturation" phenomenon: the output SINR of each of these receivers converges to a finite limit as the signal-to-noise ratio of the desired user increases, which indicates that the capacity of a wireless system with blind or group-blind multiuser receivers is not only interference-limited, but also estimation-error limited.

An analytical approximation for the probability density function of the NFR is presented, which is accurate when the ratio of users to processing gain is small and shows that the spread in SIR over the user population can be significant.

Blind adaptive interference suppression for the near-far resistant acquisition and demodulation of direct-sequence CDMA signals

TLDR
This paper presents a blind adaptive interference suppression technique for joint acquisition and demodulation, which has the unique feature that the output of the acquisition process is not simply the timing of the desired transmission, but a near-far resistant demodulator that implicitly accounts for knowledge of the timing and amplitudes of all transmissions to suppress the multiple-access interference.

TLDR
A method for timing acquisition in which the output of the acquisition process is a near-far-resistant demodulator which automatically accounts for the delays and amplitudes of both the desired signal and the interference without explicitly estimating these parameters.

It is shown that the optimum multiuser efficiency of asynchronous systems is nonzero with probability 1, and therefore the optimum demodulator does not become multiple-access limited in contrast to the single-user receiver.

Adaptive receiver structures for asynchronous CDMA systems

The proposed linear receiver is as simple as a standard single-user detector receiver consisting of a matched filter with constant coefficients, but achieves essential advantages with respect to timing recovery, multiple access interference elimination, near/far effect, narrowband and frequency-selective fading interference suppression, and user privacy.

TLDR
The receiver is shown to be immune to the near-far problem in the sense that the performance without any power control is nearly identical to the performance with perfect power control, and to offer a two-fold increase in capacity relative to a conventional receiver withperfect power control.
