Publication number: 20140018025Abstract: Provided are a receiving device, receiving method, and computer program such that good precision for signal received power estimation is achieved even during fast fading. The receiving device includes: a segmenting unit for segmenting the period the signal received power of a reception signal, i.e., a received signal, is measured in, according to characteristic values related to the power of the reception signal (for example, SNR); and a calculation unit for calculating the RSRP (signal received power) from the power of the channel estimate at each of the segment periods, i.e., the portions that the period was segmented into.Type: ApplicationFiled: March 29, 2012Publication date: January 16, 2014Applicants: NTT DOCOMO, INC., NEC CASIO Mobile Communications, Ltd.Inventor: Kazuhiro Ishida

Publication number: 20130322582Abstract: Provided is a receiving device which, even when a temporary degradation occurs in the propagation path environment during an AFC tracking operation, does not require an initial lead-in operation when the propagation path environment returns to normal and which has lower power consumption and shortened time during which communication is not possible; also provided are a receiving method and a computer program. This receiving device calculates the variance of the phase rotation angle relative to a reference signal, compensating for frequency error if the rotation angle variance is less than a pre-set threshold value (TH), and stopping frequency error compensation if the rotation angle variance is greater than or equal to the threshold value (TH).Type: ApplicationFiled: February 23, 2012Publication date: December 5, 2013Applicant: NEC CASIO MOBILE COMMUNICATIONS, LTD.Inventor: Kazuhiro Ishida

Patent number: 7698620Abstract: A calculation is facilitated for y[i]=q[i]×mod(p?1) which is required as an intermediate value when calculating intra-row permutation pattern U[i][j], which is a parameter for use by an interleaver for on a turbo code defined in a standard 3GPP TS25.212 of IMT 2000, from prime number p, base sequence s[j], inter-row permutation pattern T[i], and prime number sequence q[i]. First, index i and variable div are initialized to zero. When q[i]?div+p?1, p?1 is added to the value of div. When q[i]<div+p?1, y[i] is calculated in accordance with y[i]=q[i]?div. Index i is incremented and the foregoing processing is repeated until i reaches R.Type: GrantFiled: February 24, 2005Date of Patent: April 13, 2010Assignee: NEC CorporationInventor: Kazuhiro Ishida

Patent number: 7318184Abstract: A base sequence S(j) is not directly calculated but is indirectly calculated by the use of a numerical sequence M(n)=[v×n] mod p. A value of M(n) can be calculated by a recurrence formula without requiring modulo calculation. The value obtained is stored in a memory. M(n) satisfies S(j)=M(S(j?1)). By determining an initial value of S(j) and interleaving the value of M(n) stored in the memory, the base sequence S(j) can be calculated without modulo calculation.Type: GrantFiled: August 20, 2004Date of Patent: January 8, 2008Assignee: NEC CorporationInventor: Kazuhiro Ishida

Patent number: 7168015Abstract: A transport format determination apparatus and method determines, for each transport channel, transport formats to be used for supplying data every data-arrival-interval. A plurality of transport channels different in data-arrival-interval are free to be multiplexed with each other. A fault of data on the plurality of transport channels is detected. At least one first data-arrival-interval of at least one first transport channel is determined, based on a result of detecting fault of data on a second transport channel having a second data-arrival-interval shorter than the at least one first data-arrival-interval.
