Dynamic channel allocation techniques using adaptive modulation and adaptive antennas
نویسندگان
چکیده
This contribution studies the impact of adaptive quadrature amplitude modulation (AQAM) on network performance when applied to a cellular network, using adaptive antennas in conjunction with both fixed channel allocation (FCA) and locally distributed dynamic channel allocation (DCA) schemes. The performance advantages of using adaptive modulation are investigated in terms of the overall network performance, mean transmitted power, and the average network throughput. Adaptive modulation allowed an extra 51% of users to be supported by an FCA 4-QAM network, while in conjunction with DCA, an additional 54% user capacity was attained.

Comparative study of adaptive beam-steering and adaptive modulation-assisted dynamic channel allocation algorithms
A range of dynamic channel allocation (DCA) algorithms, namely, distributed control and locally distributed control assisted DCA arrangements, are studied comparatively. The so-called locally optimized least interference algorithm (LOLIA) emerges as one of the best candidates for future mobile systems, supporting more than twice the number of subscribers in comparison to conventional fixed chan...
متن کاملHybrid-Adaptation-Enhanced Dynamic Channel Allocation for OFDM Wireless Data Networks
In this paper, we develop the dynamic channel allocation (DCA) algorithm for multi-antenna orthogonal frequency division multiplexing (OFDM) systems in multiuser downlink data transmissions. First, focusing on the code division multiple access (CDMA)-based OFDM systems with any given spreading gain G, we design the DCA algorithm to maximize the total system throughput by employing our recently ...

This paper presents an empirical mode decomposition (EMD) based adaptive filter (AF) for channel estimation in OFDM system. In this method, length of channel impulse response (CIR) is first approximated using Akaike information criterion (AIC). Then, CIR is estimated using adaptive filter with EMD decomposed IMF of the received OFDM symbol. The correlation and kurtosis measures are used to sel...
متن کاملApproaching the Zero-Outage Capacity of MIMO-OFDM without Water-Filling
Orthogonal-frequency-division multiplexing (OFDM) transforms a frequency-selective multiple-input multipleoutput (MIMO) fading channel into a MIMO-OFDM channel that has a well-defined outage capacity. According to Shannon theory, a transmitter with channel knowledge can achieve this capacity by a combination of eigenbeamforming and water-filling; the eigenbeamforming transforms the MIMO-OFDM ch...
متن کاملQuality of Service and Dynamic Adaptive Discrete Multi-tone Modulation
In existing DMT (discrete multi-tone) systems with adaptive bit allocation a deterioration of the transmission channel may lead to increased bit error rates, and even to the loss of connection. In most cases this disturbed channel would allow a stable transmission using a new bit allocation (possibly with reduced data rate), after a further initialization phase. We propose dynamic adaptive DMT ...
