Low-cost high data-rate direct-conversion multi-port receiver for millimeter-wave indoor wireless applications
Résumé
Performance analysis of a millimeter-wave direct conversion receiver, based on the S-parameter measurement results of recently fabricated multiport circuit, is presented in this paper. In order to obtain realistic and highly accurate modeling, the measured S-parameters of the fabricated multiport are introduced in computer model using the schematic platform of Keysight's Advanced Design System (ADS). The performances in terms of Bit Error Rate (BER) are analyzed for various data-rates of a pseudorandom QPSK signal: 100 Mbps, 200 Mbps, 500 Mbps, 800 Mbps and 1 Gbps. The obtained BER results, demonstrate the effectiveness of the direct QPSK multiport demodulator for high data-rates up to 1 Gbps.
