افزایش گذردهی در کانال HF به وسیله همسانساز بازخور تصمیم با الگوریتم QRD-RLS سریع چندکاناله و استخراج ضرایب در حالت داده

Increasing data throughput of Multipath time-varying HF channel by employing decision feedback equalization is addressed. In this paper, we propose multichannel FQRD-RLS adaptive filtering algorithm employing weight extraction in Decision-directed mode. A comparison between this technique and IQRD-RLS algorithm is performed. Simulation is conducted under channel parameters with respect to MIL-STD-188-110B. The results show higher data throughput in a frame with acceptable computational cost. It is also shown that the achieved data throughput is as same as using MC-FQRD-RLS algorithm in Full-Iteration equalization mode, at a much lower computational cost.
