| Abstract(in English) | A Highspeed MLSE(Maximum Likelihood Sequence Estimation) Equalizer LSI has been developed. The LSI offsets a degradation caused by delayed signal, in case the difference of the arrival time is within 1 symbol duration. It realizes 2 branch combining diversity reception. The LSI consists of 70k gates, and operates at the power supply voltage of 3.3V. Performance test under 2 ray Rayleigh fading condition using a 6.144Mbit/s-QPSK Modem shows that the LSI limits the floor of the Bit Error Rate lower than 10^<-5> and 10^<-6>, with and without diversity reception respectively. The performance test using 54.912Mbit/s-QPSK Modem shows the usefulness of the LSI at the higher speed communication. Power consumption of the chip, which is proportional to bit rate, is 170mW at the bit rate of 10Mbit/s. |
