Abstract(in English) | We propose a semi-blind adaptive algorithm for optimization of the weighting coefficients of the receiving transversal chip-matched filter in detecting the desired signals used in direct-sequence code division multiple access(DS-CDMA)systems. In the stage for training of the proposed algorithm, the optimum weighting coefficients are derived by using the sample matrix inversion. By using the optimum weighting coefficients, fading level on the desired user's signal is estimated. In the data transmitting stage, the adaptive blind estimations of the desired signals and fading levels are executed iteratively. As the blind method, linearly constrained generalized constant modulus algorithm(LCGCMA)are adopted for preventing the signal power of the desired user from diminishing. Simulation results confirm the effectiveness of the proposed semi-blind adaptive algorithm based on SMI and CMA. |
