Uplink BER Performance Comparison of Single-carrier Multi-access and Multi-carrier Multi-access
Abstract The downlink bit error rate (BER) performances of DSand MC-CDMA in a frequency-selective fading channel can be significantly improved by the use of frequency-domain equalization (FDE) based on minimum mean square error (MMSE) criterion. However, the uplink BER performance degrades due to strong multi-user interference (MUI) since different users’ signals go through different channels a...
متن کاملA Power Constrained Multi-Channel MAC Protocol for a Cooperative Spectrum Access
The Cognitive Radio (CR) is a recent technology that aims at increasing the spectrum utilization under the current static spectrum management. With appropriate CR MAC protocols, the unlicensed users, also called secondary users (SUs), are able to access the unused portion of spectrum in an opportunistic way. These protocols should also provide a coordinated access between the SUs and protect th...
متن کاملPerformance Effects of the Uplink Asynchronism in a Spread Spectrum Multi-Carrier Multiple Access System
In this paper we investigate the effects of the asynchronism of user signals in the uplink of a spread spectrum multi-carrier multiple access (SS-MC-MA) system. Different propagation delays due to different distances between the mobile transmitters and their base station cause asynchronous arrivals of the uplink signals in addition to multipath propagation. The proposed uplink SS-MC-MA scheme u...
متن کاملPower Spectrum Optimization of Multi-Carrier MIMO Ad Hoc Networks: A Dual Stochastic Approximation Approach
Multi-carrier MIMO (MC-MIMO) has emerged as a promising technology to provide significant capacity gain for broadband wireless ad hoc networks. However, due to the non-convex and large-scale problem structure, little work has been done on power spectrum optimization to harvest MC-MIMO’s capacity gain for broadband ad hoc networks. Our principal goal in this work is to fill this challenging gap....
متن کاملImitative Policies for Reinforcement Learning
We discuss a reinforcement learning framework where learners observe experts interacting with the environment. Our approach is to construct from these observations exploratory policies which favor selection of actions the expert has taken. This imitation strategy can be applied at any stage of learning, and requires neither that information regarding reinforcement be conveyed from the expert to...
