摘要： In a reception apparatus, a matched filter that has conventionally been arranged in a searcher unit is mounted on an acquisition unit together with a large scale memory. The large scale memory once stores reception chip signals, and thereafter outputs them to the matched filter and to the delay profile calculation unit. A setting register receives an acquisition signal and outputs it to the matched filter. The matched filter performs acquisition of the reception chip signals outputted from the large scale memory, and outputs a despread timing signal to a despread circuit, a code generation circuit and the delay profile calculation unit.

摘要： In a viterbi decoding apparatus, a depuncture circuit is always synchronized with the input of a correct convolutional code irrespective of the degree of noise in the transmission path of the convolutional code. A comparator (4) makes a comparison of error numbers of slip states 1 through N stored in registers (R1) through (RN) of the register group (2), respectively, to detect a register (Rk) (k=either of 1 through N) storing the minimum error number thereby to output a minimum slip state (MINSLIP) indicating the slip state k to a slip state determination portion (5). The slip state determination portion (5) determines the minimum slip state (MINSLIP) to be a determined slip state (DSLIP) when the minimum slip state (MINSLIP) continuously indicates the same slip state M times.

摘要： A two-focal-point pickup device capable of suppressing the generation of glitch or bump in reproduced signal. The optical pickup device irradiates a light beam emitted from a light source onto an optical recording medium to form a light spot on a track of a recording surface of the optical recording medium to read the optical recording medium while controlling the position of the light spot relative to the track of the recording surface. The optical pickup device includes a converging lens section coaxially disposed in an optical axis of the light beam to converge the light beam onto the recording surface; and a hologram lens section coaxially disposed in the optical axis of the light beam to diffract the light beam. The hologram lens section has a diffraction grating pattern being formed in such a manner that a first-order diffraction light of the light beam caused by the hologram lens section and converged on the recording surface has a first numerical aperture existing in a direction intersecting the track extending direction and a second numerical aperture existing in the track extending direction. The first numerical aperture is less than the second numerical aperture.

摘要： A laser light source (61) and a heat-radiating plate (71) are provided on a pickup base (51). The laser light source (61) irradiates a laser beam to an optical disk (41). The heat-radiating plate (71) has at least one part exposed outside the pickup base (51), having a predetermined distance between the heat-radiating plate (71) and the pickup base (51), and radiates heat generated by the laser light source (61). The plate (71) can radiate heat also from a surface opposing the pickup base (51) and can therefore have a high heat-radiating efficiency.
