Abstract
This paper describes modeling and simulation of a nonlinear QPSK/TDMA digital satellite channel and burst-mode link analyzer (BMLA) by use of novel computational and least squares (LS) approaches on a VAX 11/780 computer. The application is to channel equalization. In this paper, some valuable simulation results are given, most of which, such as on the BMLA with LS algorithm and on the effects of nonlinearity and quantization wordlength, were acquired for the first time. Emphasis is placed on the introduction of the BMLA/LS to impulse response extraction, and on the comparison and evaluation of the test results, which confirm the possibility of the BMLA/LS applications in a digital communication channel and confirm this simulation system as a powerful tool for QPSK/TDMA link analysis and channel equalization.
