چکیده
ADSL(Asymmetric Digital Subscriber Line) transmission technology meets internet access requirement quite well and offers telephone companies a technology for connecting virtually all internet users at megabit rates.The ANSI (American National Standara Institute) proposes discrete multitone (DMT) modulation with DFT (discrete Fourier tranasform) bases [l] as the carriers for the ADSL system. Recently, discrete wavelet multitone modulation has been studied with non-blind and blind equalization schemes [2,3,4]. In the present paper, we propose an entirely different approach which combines the multitone modulation and optimal orthonormal subband coding.

Efficient Multi-Carrier Communication on the Digital Subscriber Loop
This thesis explores three distinct philosophies for improving the efficiency of multi-carrier communication on the digital subscriber loop. The first topic discussed is impulse response shortening for discrete multitone transceivers. The minimum mean-squared error impulse response shortener is reformulated to allow near-optimal rate performance. It is demonstrated that the best existing eigen-...
متن کاملRecursive Least Squares Channel Estimation for Rapidly Time-Varying Scenarios in IEEE 802.11p
Rapid time-varying channel estimation is one of the biggest challenges in IEEE 802.11p standard. It is a wireless vehicular communication standard which is used for outdoor applications. This paper proposes a novel decision-directed recursive least squares (RLS) time-domain channel estimation method that utilizes the guard interval of every orthogonal frequency division multiplexing (OFDM) symb...
متن کاملAdaptive Channel Equalization for Wireless Personal Communications
In this paper, a new adaptive H1 filtering algorithm is developed to recursively update the tap-coefficient vector of a decision feedback equalizer (DFE) in order to adaptively equalize the time-variant dispersive fading channel of a high-rate indoor wireless personal communication system. Different from conventional L2 [such as the recursive least squares (RLS)] filtering algorithms which mini...
متن کاملLow Complexity Method to Estimate Co-channel Signals using an Antenna Array - Personal Wireless Communication, 1999 IEEE International Conference on
The estimation of binary, co-channel digital signals in a mobile multipath time-varying environment has been developed in [ 11. However, it is computationally expensive since it involves the Singular Value Decomposition (SVD) of large matrices. In this paper, a low-complexity variant for the estimation of cochannel binary signals has been developed, which uses Iterative Least Squares with Proje...

In this paper we analyze a recently proposed concatenated multitone system for application in the asynchronous multiple access channel (wireless uplink). We study the robustness of the scheme to the users’ time offsets, carrier frequency offsets, and channel time/frequency selectivity. A comparison with multiuser OFDM and MC-CDMA is reported which shows that increased robustness and better perf...
