  • Patent number: 9439221
    Abstract: The methods for managing access to a communication medium shared by a plurality of radio communication devices. The method of accessing a radio communication medium shared between a plurality of communication terminals. The method is based on a variant of the CSMA/CD access protocol. The method is based on monitoring of the medium and the emission of a token to request permission to emit. The terminals that receive this token then emit an acknowledgement intended to signal that the medium can be used, or a collision message if they receive a plurality of tokens simultaneously. In the latter case, the emitter retries its attempt to use the medium later on.

  • Publication number: 20140337693
    Abstract: The invention relates, according to the first form thereof, to a transmission error correction method, wherein at least two encoded binary series from a binary series that is to be transmitted and encoded by means of a convolutional code are received from a communication channel. Said method is characterized in that same comprises the following steps: producing, from two received encoded binary series, comparison binary series that coincide in the absence of transmission errors on the communication channel; comparing the comparison binary series and forming a detection binary series corresponding to the logic operation OU-exclusive of the two comparison binary series; and, in the event that the comparison binary series diverge from a divergence point, verifying if the series made up of P bits of the detection binary series from the divergence point corresponds to a listed transmission error and correcting, if necessary, the received encoded binary series.

  • Patent number: 7280067
    Abstract: The present invention relates to a radar detector and a radar detecting method for WLAN systems according to 802.11 wireless communication standards, and particularly concerns the radar detection for 802.11 h dynamic frequency selection mechanism. The essence of the innovation consists in projecting the received phase vector on the signal subspace orthogonal to the expected radar pulse subspace and taking the norm of the resulting vector. The closer the norm is to zero, the more likely the received signal is to be a radar pulse. The invention is able to detect both, sinusoidal radar signals and chirp-like radar signals.

  • Publication number: 20060203926
    Abstract: A novel method and apparatus for short preamble detection within the framework of the 802.11a standard is described. The present invention can be easily implemented in both the radio part (preferred embodiment) and the baseband part (general case) of the receiver to provide short preamble detection. The inventive method and apparatus utilize either a notch comb filter to remove the rake of subcarriers composing the short preamble or a battery of bandpass filters to enhance them. A decision on the presence of the short preamble is made by comparing the magnitude associated to certain qualities of the input and output sequences to a preset threshold. The proposed innovation offers a significant advantage over conventional approaches in terms of gate count and power consumption.

  • Publication number: 20060198473
    Abstract: The present invention relates to the field of wireless communication systems and in particular to an apparatus and a method for short preamble detection within the framework of the 802.11b standard. The present invention can be easily implemented in either the radio part (preferred embodiment) or the baseband part (general case) of a wireless LAN receiver to provide short preamble detection. The inventive method and apparatus utilize a couple of low-complexity cross-correlators respectively fed by an oversampled I and Q signal to detect the presence of a short preamble. A decision on the presence of the short preamble is made by comparing a figure of merit formed by adding the magnitude of the largest peaks respectively yielded by both cross-correlators to a preset threshold. The proposed innovation offers a significant advantage over conventional approaches in terms of gate count and power consumption.

  • Publication number: 20060199558
    Abstract: The present invention relates to the field of wireless communication systems and in particular to an apparatus and a method for detecting preambles according to IEEE 802.11a/b/g wireless LAN standards and its application to an 802.11 multimode receiver. The proposed apparatus is capable of detecting 802.11a/b/g preambles by using two auxiliary low-resolution ADCs (down to 1 bit) coupled with a preamble detector. The purpose of this apparatus which is located within the RF section of the receiver upstream of the baseband section, is to offload or discharge the baseband functions by performing a signal discrimination and waking up the baseband functions only if the received signal is determined to embed either an 802.11a/g or 802.11b preamble. This results in significant power savings in a multimode 802.
