Abstract
The potential of turbo-equalization technique applied to uplink (UL) LTE signals detection is analyzed in this paper. The turbo equalizer, which is also called iterative receiver, represents a popular approach for detection of signals passed through a fading channel. The receiver performs equalization and decoding of error-correcting code in a loop. For implementation of the iterative receiver we performed two frequency-domain equalizers: the approximate MMSE SISO-equalizer and the soft interference canceller (SIC) SISOequalizer. During the simulation, we analyzed several configurations of UL LTE with QPSK, 16-QAM, 64-QAM signal constellations and allocation of 25 and 100 resource blocks. All considered modes used rate 2/3 parallel concatenated convolutional code and single input single output antennas pattern. Bit error rate (BER) performance was estimated during the simulation with the extended vehicular A (EVA) model of multipath fading channel.
