| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | This paper presents basic investigations on the automatic impedance matching implemented in a 4-branch MRC array used for a digital broadcasting portable TV set. In the first step, three-dimensional estimation functions were evaluated by theoretical analysis in order to investigate the possibility of adopting the gradient method as an optimization algorithm. Considerations were also given on the stability and convergence properties of the algorithm. Moreover, we consider the insertion loss of a varactor diode used in the matching circuit. Finally, assessments of communication quality, such as the signal bit error rate (BER), were conducted to gain useful knowledge of the way and the degree to which the proposed automatic impedance matching might impact the reduction of the signal-to-noise ratio (SNR) for achieving the prescribed BER. | |
