In this research, STANAG 4285 HF modem software is implemented on TMS320C54x fixed point digital signal processor. The software is optimized in order to meet real-time operation requirements. A fractionally spaced least mean square (LMS) decision feedback equalizer (DFE) is employed for the receiver. In order to improve the convergence of the LMS algorithm a multipass technique is utilized. Based on Watterson̕s model, an HF channel simulator is employed for evaluating the performance of the modem. The simulation results show that the convergence of the LMS algorithm is improved by using multipass technique. It is also shown that the software meets the real-time operation requirements.
