چکیده
Adaptive modulation is a method to increase the data capacity, throughput and efficiency of time division duplexed wireless communication systems. In adaptive modulation, the transmitter continually monitors the dynamic channel and adjusts the transmission parameters such as modulation order, coding rate etc. accordingly. Blind modulation detection schemes play an important role in adaptive systems to eliminate the need for transmitting modulation information, thereby increasing spectral efficiency. In this paper, an improved statistical blind modulation detection method based on the Kullback-Leibler distance is proposed for OFDM based wireless communication systems. Simulation results show that this blind modulation detection algorithm outperforms similar previously proposed algorithms.

Repeatability of large-scale signal variations in urban environments - Vehicular Technology Conference, 2003. VTC 2003-Fall. 2003 IEEE 58th
This paper quantifies the repeatability of largescale signal variations in an urban propagation environment. We propose a model and use field measurements taken in downtown San Francisco to quantify how similar the received signals appear when a mobile receiver revisits the same general area. The results establish bounds for repeated measurements within a given street that are taken on differen...

In this paper, a pilot assisted minimum mean square error multiuser channel estimation algorithm is proposed for quasi-synchronous CDMA systems. The doubly selective multiuser fading channel is represented as a time-varying chip-spaced tapped delay line filter with correlated filter taps. The multiuser channel tap coefficients at pilot symbol positions are estimated under the MMSE criterion wit...

In this paper we analyze the performance of ADHOC MAC, a new MAC protocol proposed within CarTALK200, a European research project with the purpose to design novel solutions for inter-vehicle communications. ADHOC MAC has been devised to provide a reliable single hop broadcast channel overcoming the hidden terminal problem, and an effective multi hop broadcast service by exploiting the connectiv...

Mobile IPv6 (MIPv6) allows a Mobile Node to talk directly to its peers while retaining the ability to move around and change the currently used IP address. This mode of operation is called Route Optimization (RO), as it allows the packets to traverse a shorter route than the default one through the Home Agent. In Route Optimization, the peer node learns a binding between the Mobile Node’s perma...
متن کاملWindow function and interpolation algorithm for OFDM frequency-offset correction
In orthogonal frequency-division multiplexing (OFDM) digital communication systems, an uncorrected frequency offset can lead to a severe degradation of the system performance. This paper describes a technique to mitigate the influence of frequency offset on system performance by applying a weighted discrete Fourier transform (DFT) to a novel OFDM frequency-assignment scheme in which null carrie...
