  • Patent number: 10236919
    Abstract: A method for bit interleaving is provided. A method includes mapping a set of bits a?{ak: k=0, 1, 2, . . . Npost?1} to an array B={Bi,j: i=0, 1, 2, . . . , M?1; j=0, 1, 2, . . . , N?1} such that bit ak maps to Bk mod M, ?k/M?, wherein mod denotes the modulo operator, ? ? denotes the floor operator, and M and N are constants, performing at least one of—a first permutation operation comprising permuting two or more bits within each of one or more first groups of bits, wherein each first group of bits is defined by G(1)p={Bi,p: i=0, 1, 2, . . . , M?1; p?{0, 1, 2, . . . , N?1}} and—a second permutation operation comprising permuting two or more bits within each of one or more second groups of bits, wherein each second group of bits is defined by G(2)q={Bq,j: j=0, 1, 2, . . . , N?1; q?{0, 1, 2, . . . , M?1}} and de-mapping bits from B to obtain an interleaved set of bits b?{bk: k=0, 1, 2, Npost?1} such that bit Bi,j is de-mapped to bit bNi+j.

  • Patent number: 8498580
    Abstract: A method for estimating qualities of links between a transmitter and a receiver on respective carrier frequencies in a multi-carrier wireless communication system from measurements made during a scanning interval in which pilot signals may be transmitted from the transmitter to the receiver in a plurality of carrier-time bins, each carrier-time bin corresponding to a respective carrier frequency of the multi-carrier system and a respective time slot within the scanning interval, are provided.

  • Patent number: 7894776
    Abstract: The invention proposes a study of how the inaccurate knowledge of the propagation conditions and interferences and noise, affecting the received signal of a radio transmission, affects the reception and a measurement model used to estimate the quality of the transmission, in a digital radio signal receiver. Actual means to correct the measurement model and improve the accuracy of the estimation of the error rate, or any other indicator of the quality of the transmission, are proposed along with a device comprising such means.

  • Patent number: 7835473
    Abstract: A method of determining a metric for evaluating an error probability of a data frame includes receiving, at a radio receiving device, the data frame encoded according to a coding method and transmitted through a radio communication channel by a radio transmitting device. The data frame includes a plurality of symbols. The method also includes performing a channel equalization of the data frame received at the radio receiving device to produce a channel equalized data frame, performing a symbol de-mapping of symbols in the channel equalized data frame to produce a de-mapped data frame, obtaining soft bits based on the de-mapped data frame and characteristics of the coding method, and calculating the metric from at least one moment, having an order strictly greater than one, of quantities that characterize an equivalent communication channel for the soft bits.

  • Publication number: 20090176456
    Abstract: The present invention concerns a method and a device for transferring power information and preferably information related to interference components received by a first telecommunication device and power information used by the first telecommunication device for weighting at least one pilot signal transferred by the first telecommunication device to a second telecommunication device, the first and the second telecommunication devices being linked through a wireless telecommunication network, the at least one pilot signal being preferably further weighted by the information related to interference components received by a first telecommunication device. The first telecommunication device transfers plural weighted pilot signals at a first rate and transfers plural power information at a second rate which is strictly lower than the first rate.

  • Publication number: 20060146946
    Abstract: The present invention concerns a method of determining a metric for evaluating an error probability of a data frame transmitted by a first device to a second device through communication channels, a data frame comprising a plurality of symbols, wherein the metric is determined at least from at least one moment of an order strictly upper than one of quantities characterising the equivalent communication channels for the plurality of items of information obtained from symbols comprised in the data frame. The present invention concerns also the associated device.
