摘要： An image transmitting remote object examination device includes (a) an image-recording system at the location of the object to be examined, (b) an observation station located at a distance from the image-recording system for the evaluation of the image and for the remote control of the image-recording system, and (c) an intervening, narrow band telecommunications link, by way of which the images taken are transferred to the observation station using image data compression and/or reduction together with the remote control commands to the image system. A system status-determining unit continuously records the overall system status relevant to image transmission, and dependent upon the overall system status, variably controls the image data compression and/or reduction and/or the number of individual telecommunication channels used in a transmission packet. The image quality required for a particular situation, together with the optimal on-line image impression, is thereby obtained.

摘要： A system for and method of providing optimizing the antenna patterns on a first satellite and a second satellite that operate in conjunction to deliver content to a single radio receiver. The process begins by first selecting an objective predictive model for predicting link margin at a first location and a link margin at a second location. The model is used further to determine an initial required transmit power flux densities to achieve the first and second link margins. Then the power flux density is adjusted for the first location by decreasing the power flux density for the first satellite and simultaneously increasing the power flux density for the second satellite. The predicted joint availability for the first location is then predicted. In the event the required power flux density cannot be achieved to achieve a desired joint availability across an entire geographical region, the power flux density for both the first and second satellites for the first location are decreased.

摘要： Received signal strength detecting means 109 and 110 detect received signal strength of the antennas of the respective terminals. A transmission antenna selector 111 selects an antenna with a maximum received signal strength with respect to the respective communication destinations, and when there is a plurality of communication destinations having the same antenna with a maximum received signal strength, the transmission antenna selector selects transmission antennas to be different from each other based on the received signal strength of the antennas with the second largest received signal strength, and an internal switch of a transmission antenna change device 114 is changed based on the selection result. This eliminates the need for providing mixers without reducing transmission diversity effect, and results in a reduction of a maximum output of a transmission amplifier.

摘要： A method and apparatus for space-time coding signals for transmission on multiple antennas. A received input symbol stream is transformed using a predefined transform and transmitted on a first set of N antennas. The same input symbol stream is then offset by M symbol periods to generate an offset input symbol stream. The offset input symbol stream is then transformed using the predefined transform and transmitted on a second set of N antennas. A third through Xth set of N antennas may be utilized for transmission by successively offsetting the offset input symbol stream by an additional M symbol periods for each additional set of N antennas used, before performing the transform and transmitting on the additional set of N antennas.

摘要： The present invention provides a method for controlling a communication parameter in a channel through which data is transmitted between a transmit unit with M transmit antennas and a receive unit with N receive antennas by selecting from among proposed mapping schemes an applied mapping scheme according to which the data is converted into symbols and assigned to transmit signals TSp, p=1 . . . M, which are transmitted from the M transmit antennas. The selection of the mapping scheme is based on a metric; in one embodiment the metric is a minimum Euclidean distance dmin,rx of the symbols when received, in another embodiment the metric is a probability of error P(e) in the symbol when received. The method can be employed in communication systems using multi-antenna transmit and receive units of various types including wireless systems, e.g., cellular communication systems, using multiple access techniques such as TDMA, FDMA, CDMA and OFDMA.

摘要： In order to improve the subscribing of telecommunication devices at cooperating stations connectable to the telecommunication devices by wireless telecommunication in wireless telecommunication systems, particularly DECT mobile parts at DECT base stations in DECT systems, all base stations transmitting received radio messages that have set and transmitted the “a44” bit are stored as in the mobile part, and a known log on procedure is implemented with a base station selected according to predetermined reception criteria. When this log on procedure miscarries, then this base station is marked as “invalid” and the same procedure, including the log on procedure, is implemented with a different base station. What is thereby utilized is that, in the log on, a PIN word and/or an AC word is interrogated. When the PIN word/AC word is incorrect, then the log on attempt is rejected. Otherwise, when the PIN word/AC word is correct, the mobile part has been successfully logged on at the base station.

摘要： A method and apparatus for wireless transmission of a digital bit stream. The present method employs diversity techniques to minimize multipath fading. Digital bits are converted into symbols and the symbols are provided to a number of diversity branches. Each diversity branch has its own antenna. The symbols sent to each diversity branch may be multiplied by a different phase factor or amplitude factor. The phase factors and amplitude factors may be randomly selected. Also, wireless channels can be monitored for channel quality. In this case, the channel quality measurements are used to select the phase factors and the amplitude factors. Also, the symbols can be grouped into frames before transmission. In this case, the frames can be multiplied by matrices comprising phase factors and amplitude factors. Also in this case, the frames can undergo cyclic shifting, which provides an additional measure of diversity.
