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.

摘要： The invention proposes a built-in self-testing method of a near field communication device including several functions (31, 32, 33), comprising testing (S1) a first internal communication link (L1) between a first function (32) and a second function (33), by sending (S11), on said first internal communication link (L1), a first command from said first function (32) used as a transmitter to said second function (33) used as a receiver, and by checking (S12) said first command has been correctly executed by said second function (33).
