Reduced-Complexity Robust Detector in a DHA FH OFDMA System under Mixed Interference
Future generation communication systems will have to endure interference induced by communication systems operating within the same frequency bands. Recently several coded DHA FH OFDMA systems employing rank-based detectors able to solve this problem were proposed. Unfortunately such detectors have relatively high complexity. In what follows a reduced-complexity detector using only column sorting for a coded DHA FH OFDMA employing a nonbinary convolutional inner code is proposed. The proposed detector is compared with the rank convolutional detector in terms of performance, complexity and delay.
