A fluorescence concentrator system that provides for high brightness light source. According to some embodiments, a wireless terminal or other wireless device can make adjustments to a measurement made from a radio transmission source by adjusting timing measurements using a weighted average andor synchronizing its timing to the timing of this or some other radio transmission source. When the successive frame error number outputted form the counter portion 17 is less than or equal to a preset reference successive frame error number, a first switch SW1 and second switch SW2 are set to an emphasis processing portion 15 side. A determination is made from a mapping of at least one user interface API corresponding to the determined standard API interface. The second routes are associated with the second connection, and have priority over the first routes. The DBB receiver includes a demodulator, first and second analog low pass filters, first and second digital gain control circuits, and a digital time domain compensation module which removes group delay variation distortion, introduced by the first and second analog LPFs, from real and imaginary signal components of the communication signal.
