For coded data transmission over channels introducing inter-symbol interference, one approach for joint equalization and decoding in the receiver is Turbo Equalization. We rederive existing linear equalization algorithms applicable to Turbo Equalization for 2m-ary signal alphabets and compare their computational complexity. Moreover, by evaluating the algorithm performance properly, we select f...

Per tone equalization was recently proposed as an alternative equalization structure for multicarrier systems. In this paper we propose two NLMS based variable length per tone equalization algorithms. In the first algorithm, the number of equalizer taps used in every subchannel is determined according to channel conditions which results in a reduction in equalization complexity. While the secon...

Abstract Recently, frequency-domain equalization (FDE) at a receiver has been attracting attention for improving the SC transmission (e.g., DS-CDMA) performance in a frequency-selective fading channel. Authors have been studying frequency domain pre-equalization at a transmitter as an effective technique to improve the transmission performance. In this paper, a pre-equalization transmission in ...

energy consumption is very high in greenhouses mainly due to off-season production. the main source of its energy supply is fossil fuels. due to the disadvantages of fossil fuels consumption and preventive laws in the incoming years, study on reducing consumption and replacing a part of them with renewable energy is essential. in this research, a solar heating system, equipped with a concentrat...

An overview on equalization schemes applicable for point-to-point communication over MIMO ISI channels is given, i.e., channels which suffer form both, multiuser interference between the data streams transmitted in parallel and intersymbol interference due to the dispersive (frequencyselective) nature of the channel. Spatial, temporal and combined spatial/temporal equalization strategies for de...

In this paper, two popular adaptive equalization methods, fractionally spaced decision feedback equalization (FSDFE) and maximum-likelihood sequence estimation (MLSE), are investigated for the design of digital mobile receivers for the IS-54 specifications of the NADC* system. A bi-directional equalization technique is incorporated and a multiple training LMS (MT-LMS) algorithm is used as the a...
