Performance Analysis of Downlink Power Control in CDMA Systems
نویسندگان
چکیده
Three downlink power control algorithms have been studied and evaluated in this work. Additionally, an uplink power control algorithm has been modified and adapted for downlink. An enhancement has been proposed to one of the studied algorithms based on the concept of hysteresis to mitigate oscillations observed at low outage probabilities in the existing algorithms. It has been shown that the behavior of outage with number of iterations in the modified algorithm converges as rapidly as the original algorithm; however the oscillations at low outage percentages have been mitigated using this enhancement.

Performance Analysis of ZF Pre-Coder and Extended Joint Channel Estimation Method in Downlink CDMA with HPA
In the down link scenario of code division multiple access (CDMA) systems, multi user detectors (MUDs) such as linear de-correlating detector (LDDs) provide satisfactory symbol error rates (SERs) at the expense of much increased complexity, they require all active users’ spreading sequences, which is impractical from privacy point of view. To overcome this impracticality, a simple matched filte...
متن کاملCapacity analysis of uplink and downlink in multimedia DS-CDMA Systems based on constraint models
Capacity analysis in wireless communication systems is essential for system design, call admission control and radio resource allocation. Since CDMA is a kind of powerconstrained or interference-limited system, its system capacity is not so “hard” as in bandwidth-limited systems, such as TDMAbased systems. In this paper, we analyze the uplink and downlink capacity of multimedia DS-CDMA systems ...
متن کاملOn the High Altitude Platform (HAP) W-CDMA System Capacity
The performance of a downlink power control model, based on a n-th power distance law, is evaluated for high altitude platform station (HAPS) W-CDMA systems. The downlink capacity using this model is compared with the uplink capacity. It is shown that the uplink capacity is higher than the downlink capacity.
متن کاملOpen-loop power control error in cellular CDMA overlay systems
Adaptive power control has widely been used in DS/CDMA systems to overcome the so-called “near-far” problem. This paper studies the adaptive open-loop power control of a cellular CDMA system, which is overlaid in the downlink by a narrowband signal. The effects of downlink power allocation schemes to power control error in the presence of narrowband interference are analyzed. In order to get a ...
متن کاملOn the downlink capacity of TDD CDMA systems using a pre-Rake
The Pre-Rake technique for the downlink transmission in TDD-based CDMA wireless systems has been shown to provide greater capacity and a simpler receiver design at the mobile receiver. Nevertheless this technique is very affected by fast changing channels, since it relies on uplink channel measurements for the downlink transmission. In this paper a semi-analytical approach to the performance, i...
متن کاملDownlink Beamforming Method for Multimedia CDMA/TDD Systems
This paper proposes a downlink beamforming method for multimedia CDMA / TDD systems. The proposed method determines the transmission weights so that the total transmitted power is minimized under a power-controlled CDMA system. In the decision process of downlink beamforming, each user’s target signal-to-interference-plusnoise ratio(SINR) and the number of RAKE fingers are considered. Numerical...
