Abstract: A LIDAR 1 includes: a scanner 55 that emits outgoing light Lo while changing the outgoing direction thereof; a reflection member 8 that is arranged in a first outgoing direction and reflects the outgoing light Lo; an absorption member 7 that is arranged in a second outgoing direction and absorbs the outgoing light Lo; an APD 41 that receives return light Lr; and a DSP16. The DSP 16 generates replica u representing a component reflected by the absorption member 7 on the basis of output signals of the APD 41 obtained at each time when the outgoing light Lo is emitted in the first outgoing direction and in the second outgoing direction.

Abstract: A lidar 1 is provided with: a scanner 55 which emits an outgoing light Lo; a dark reference reflective member 7 which is arranged in a predetermined emitting direction and which absorbs the outgoing light Lo; an APD 41 which receives the return light Lr that is the outgoing light Lo reflected by an object; and a DSP 16. The DSP 16 estimates at least a receiver noise on the basis of the output signal of the APD 41 in the dark reference period Td when the dark reference reflective member 7 is irradiated with the outgoing light Lo. Then, on the basis of the estimated receiver noise, the DSP 16 applies a filtering to the output signal of the APD 41.

Abstract: A lidar 1 is provided with an APD 41 and a DSP 16. The APD 41 receives a return light Lr that is an outgoing light Lo radiated by a scanner 55 and thereafter reflected by an object. The DSP 16 includes a shot noise estimation unit 77 and a voltage control unit 78. The shot noise estimation unit 77 estimates, on the basis of the output signal from the APD 41, information associated with background light amount that is the sun light reflected by the object and thereafter received by the APD 41. The voltage control unit 78 determines, on the basis of the information associated with the estimated background light amount, the voltage to be applied to the APD 41 in order to control the gain M of the APD 41.

Abstract: On the basis of a segment signal Sseg outputted by a core unit 1, a signal processing unit 2 of a LIDAR unit 100 generates a polar coordinate space frame Fp indicating the received light intensity of laser light with respect to each scan angle that indicates the outgoing direction of the laser light and its corresponding target distance Ltag. Then, the signal processing unit 2 converts the polar coordinate space frames Fp into an orthogonal coordinate space frame Fo and outputs it to a display control unit 3. Further, for an outgoing direction of the laser light in which the segment signal Sseg outputted by the core unit 1 indicates a received light intensity equal to or larger than a threshold Apth, the signal processing unit 2 generates the measurement point information Ip and outputs it to a point group processing unit 5.

Abstract: A sum of products calculation of a predetermined tap number of tap data and a prescribed tap number of coefficients is carried out and a sum of the predetermined number of tap data is calculated. A replica signal is calculated on the basis of the sum of products calculation result, the sum of the tap data, and a correction coefficient. A residual signal is calculated as the difference between the replica and received signals. The predetermined tap number of coefficients is updated based on the predetermined tap number of tap data and the residual signal, and the correction coefficient calculated from the residual signal. Here, the tap data is either a data symbol before the superimposition of a DC component or an estimation thereof. This allows an adaptive FIR filter used in channel estimation of a received signal by a digitally modulated wave whereupon a DC component is superimposed.

Abstract: The present invention calculates an echo profile on the basis of: a complex baseband signal generated in a front end (2#b) on the basis of a received signal transmitted by an antenna (1#b); and a transmission symbol estimated value (dfin) supplied by a trellis decoder (8). With the estimated transmission symbol (dfin) as a filter input, the echo profile is calculated on the basis of a filter coefficient of an adaptive filter having a received signal as the desired filter-output signal. On the basis of the calculated echo profile, a sampling-frequency control unit (10) controls the sampling frequency of the baseband signal in the front end (2#b). As a result, it is possible to perform a highly accurate timing-recovery control.

Abstract: A CFR estimation unit estimates channel frequency characteristic on the basis of a complex baseband signal provided by a front end via a data distribution unit, and a transmission symbol estimated value provided by a trellis decoder. On the basis of the channel frequency characteristics estimated in this manner, a carrier frequency control unit performs a carrier recovery control in order to become the carrier frequency error to zero in the front end, by performing an Auto Frequency Control based on changes in the channel phase in the full band of the frequency. As a result, carrier synchronization is performed appropriate for mobile receiving, and receiving performance is improved, even in the case of a digitally modulated signal having a DC pilot component by a single carrier.

Abstract: A receiver having a high frequency selectivity noise tolerance is achieved on a small calculation scale by way of an received signal spectrum (RSS) calculation part, that calculates a received signal spectrum on the basis of a complex baseband signal (CBB) signal transmitted from a frontend, a channel frequency response (CFR) estimation part, that calculates an estimated channel characteristic and a residual signal on the basis of the CBB signal and estimated transmitted symbols estimated by a trellis decoder, and a noise power spectrum (NPS) estimation part, that calculates an estimated noise power spectrum on the basis of the residual signal calculated by the CFR estimation part. A combination part combines a plurality of received signal spectrums on the basis of the received signal spectrum, estimated channel characteristics and estimated noise power spectrum. An equalization part performs equalization of the combination result, thereby calculating an equalized spectrum.

Abstract: A CFR estimation unit (13) estimates channel frequency characteristic on the basis of a complex baseband (CBB) signal provided by a front end (2#b) via a data distribution unit (11), and a transmission symbol estimated value (dfin) provided by a trellis decoder (8). On the basis of the channel frequency characteristics estimated in this manner, a carrier frequency control unit (15) performs a carrier recovery control in order to become the carrier frequency error to 0 in the front end (2#b), by performing an Auto Frequency Control (AFC) based on changes in the channel phase in the full band of the frequency. As a result, it is possible to perform carrier synchronization appropriate for mobile receiving, and to improve receiving performance, even in the case of a digitally modulated signal having a DC pilot component by a single carrier.
