发明名称 Built-in self-test technique for detection of imperfectly connected antenna in OFDM transceivers
摘要 OFDM communication transceiver having a receiver chain and an emitting chain, adapted to test its connection with an antenna circuit unit (11), the receiver chain comprising a time-to-frequency transform unit (15) and the emitting chain comprising a frequency-to-time transform unit (6), and the transceiver further comprising: - Means for disconnecting the receiver chain to the antenna circuit unit (11); - Means for providing a stimulus as input to the emitting chain; - Means (22, 23) for reintroducing the signal at the output of the emitting chain as an input of the receiving chain; - Means (24) for determining a resonance frequency, Fr, and a quality factor, Q, of a transfer function computed from the output of the time-to-frequency transform unit (15); - Means for deciding (25, 26) about the connection of said antenna circuit unit (11) according to these resonance frequency and quality factor.
