    Abstract: Provided is a feature such that the opportunity to cancel travel control can be reduced by seamlessly switching between travel modes in combination with a plurality of functions. A travel control device has: a first mode which causes a vehicle to travel according to the control target set on the basis of an object outside the vehicle; and a second mode which causes the vehicle to travel according to the control target set irrespective of an object outside the vehicle. If it is impossible to set the control target on the basis of the object outside the vehicle during traveling in the first mode, the travel mode is shifted to the second mode. If it is possible to set the control target on the basis of the object outside the vehicle during traveling in the second mode, the travel mode is shifted to the first mode.

  • Patent number: 8964777
    Abstract: In a radio communication system where a base station provides blank time slots to avoid inter-cell interference, a decrease in throughput by an excess or shortage of blank time slots is prevented. This invention relates to a radio system that avoids interference in cooperation between base stations by providing blank time slots by a (first) base station. Other (second) base stations detect the number of served terminals affected by interference from the first base station that sets blank time slots, calculate required blank time slots so that the number of required blank time slots will increase with an increase in the number of terminals located in cell edges, and send a notification of the required blank time slots to the first base station. The first base station determines whether system throughput is anticipated to improve, based on the above notifications, and adjusts the length of blank time slots.

  • Patent number: 8494076
    Abstract: In a MIMO wireless communication system, the transformation process synthesizes the eigenmodes having a large singular value (i.e. a high effective SNR) and the eigenmodes having a small singular value (i.e. a low effective SNR). Thereby, the former eigenmodes are converted into modes having suppressed effective SNR which do not require a large number of levels of modulation, and the latter eigenmodes are converted into modes having increased effective SNR instead. In a MIMO wireless communication system for eigenmode transmission, a large communication capacity is realized without increasing the number of levels of modulation even in a communication environment capable of achieving a high SNR.

  • Patent number: 8345785
    Abstract: In MIMO transmission between M transmission antennas and N reception antennas, a transmission signal vector is set as a vector having 2M elements comprising in-phase components and quadrature components of M complex signals, a reception signal vector is set as a vector having 2N elements comprising in-phase components and quadrature components of N complex signals, and a transfer matrix is set as a real matrix comprising 2N rows and 2M columns. Then, a transfer matrix containing IQ mismatch is obtained based on a training signal, thereby executing MIMO encoding and decoding. For learning of the transfer matrix, a training signal which has two linearly-independent signal points on a constellation for each of the transmission antennas is used. With such an arrangement, in MIMO transmission, IQ mismatch in a quadrature modulator and a quadrature demodulator can be compensated and a bit error rate can be improved.
