High-speed power-efficient indoor wireless infrared communication using code combining .I
IEEE Transactions on Communications - Tập 50 Số 7 - Trang 1098-1109 - 2002
K. Akhavan, M. Kavehrad, S. Jivkova
While use of power-efficient signaling schemes appears to be effective at compensating for the inherent high path-loss associated with pure diffuse infrared links, it begins to lose its effectiveness as the data rate is increased. At very high data rates, intersymbol interference (ISI) can result in a very high and sometimes irreducible power penalty, preventing the system from operating at a low ... hiện toàn bộ

The mean-square delayed decision feedback sequence detector
IEEE Transactions on Communications - Tập 50 Số 9 - Trang 1462-1470 - 2002
M. Magarini, A. Spalvieri, G. Tartara
In signal equalization, a detection technique that allows reduction of the number of states of the Viterbi (1979) detector is the delayed decision feedback sequence detector (DDFSD). In order to achieve good performance, it is crucial to operate an appropriate prefiltering of the received sequence before the DDFSD. The main novelty of the paper is performance evaluation of the DDFSD when the feedf... hiện toàn bộ

Analysis of hybrid selection/maximal-ratio combining in correlated Nakagami fading
IEEE Transactions on Communications - Tập 50 Số 8 - Trang 1372-1383 - 2002
R.K. Mallik, M.Z. Win
We present an analysis of a hybrid selection/maximal-ratio combining diversity system over an evenly correlated slow frequency-nonselective Nakagami fading channel, where the correlation coefficient between any pair of the diversity branch gain amplitudes is the same, and all average branch signal-to-noise ratios (SNRs) are equal. In this system, the L branches with the largest instantaneous SNR o... hiện toàn bộ

Iterative multiuser detection with integrated channel estimation for coded DS-CDMA
IEEE Transactions on Communications - Tập 50 Số 8 - Trang 1217-1223 - 2002
A. Lampe
A practically interesting approach for iterative channel estimation, multiuser detection, and single-user decoding based on maximum a posteriori symbol-by-symbol estimation for direct sequence/code-division multiple-access (DS-CDMA) is proposed. The receiver relies on the output of a bank of matched filters for each user and each path, and combines interference cancellation with iterated soft-deci... hiện toàn bộ

Bandwidth-constrained signature waveforms and Walsh signal space receivers for synchronous CDMA systems
IEEE Transactions on Communications - Tập 50 Số 7 - Trang 1137-1149 - 2002
H.H. Nguyen, E. Shwedyk
Synchronous CDMA systems whose transmission bandwidth is quantified through the fractional out-of-band energy (FOBE) constraint are considered. Either a conventional matched filter (MF) receiver or a minimum mean-square error (MMSE) receiver is employed for users' data detection. The total squared correlation (TSC) and the total mean-square error (TMSE) are proposed as the performance parameters f... hiện toàn bộ
