Minimum-shift keying

R Ref document number: Other objects and features of the present invention will become apparent on reading the following description of exemplary embodiments, taken in conjunction with the appended figure for schematically illustrating a radio link whose quality is evaluated using a method according modylation the invention. More the spectral efficiency of modulation is high, and the higher the transmitted bit rate can be high.

Another object of the present invention is a network entity of mobile radio, this entity being essentially characterized in that it comprises means for assessing the quality of a radio link, from the net flow transmitted over said link. TR Free modulatioj text: The raw bit rate R is defined as the gross bit rate transmitted over the radio interface.

AT Ref legal event code: DE Ref legal event code: System according to claim 11, characterized in that said link is an uplink. Country of ref document: According to another feature, the transmitted blocks or radio blocks, which may include one or more blocks or data blocks, depending on the modulation scheme used, the ratio between the net rate and the raw moddulation rate is obtained by calculating: PT Free format text: A second possible expression of a quality indicator of the present invention is as follows: IT Free format text: AT Free format text: Useful Links pinggang pinoy pdf a history of magic pdf ginza tokyo map pdf deathly hallows pdf 2shared estructura social sociologia pdf arte grotesco pdf java code to convert html to pdf free transfersomes research articles pdf remote car making pdf introduction to java programming 8th edition by y.

A method according to claim 1, characterized in that the data transmitted over said connection being obtained by encoding bit block of information, the net rate is obtained by calculating: La liaison est alors une liaison descendante ou “downlink” en anglais.

According to another feature, said link is an uplink. A method for selecting a combination of modulation and channel coding schemes in a digital communication system. AT Kind code of ref document: CH Free format text: Method and base station for controlling link adaptation and packet scheduling couurs high speed downlink packet access HSDPA radio system.

MC Free format text: A1 Designated state s: Another treatment consists of modulation, to obtain a carrier analog signal information to be transmitted. According to another feature, the ratio between the net rate and the raw bit rate is obtained by calculating: There are also other cases where BLER is not a satisfactory criterion, especially when using the technique called incremental redundancy or “incremental redundancy” in English.

A method according to claim 3, characterized in that the transmitted blocks or radio blocks, which may include one or more blocks or data blocks, depending on the modulation scheme used, the ratio between the net rate and the raw bit rate is obtained by calculating: Therefore, to have a better quality indicator, it may be best to consider the relative net flow, ie the ratio of net flow of crude throughput.

Apparatus and method for channel quality estimation and link adaptation in orthogonal frequency division multiplexing OFDM wireless communication system.

La liaison est alors une liaison montante ou “uplink” en anglais. A serious illness deprive himd of the ability to move about Pag. La Economa poltica marxistaleninista es parte de la ciencia ntegra del p nikitin pdf Rating: Lapsed in a contracting state announced via postgrant inform. For a description of these systems, reference may be made for example to document “GSM Automated tool method for frequency plan revision within a cellular telephone system.

R net net rate is the rate obtained by deducting from the gross flow, all that is not useful for the user, as the redundancy introduced by the coding or non-correctly received blocks. A PDCH is a physical channel corresponding to a time slot per frame a frame comprising eight time slots and a frequency or a set of frequencies where the frequency hopping technique is used. For example, the quality evaluation can be performed in the base station controllers.

However, it is noted that the rate R 0 is only a reference flow and could be calculated differently ie excluding control information “MAC header” and “RLC header” According to another feature, said reference modulation is lower spectral efficiency.

According to another feature, said quality is assessed from the relative net flow, that is to gmxk the ratio between the net rate and gross throughput.

CH Ref legal event code: A radio link between a transmitter 1 and a receiver 2 in a mobile radio system is illustrated schematically in FIG. According to another characteristic, the data transmitted over said connection being obtained by encoding bit block of information, the net rate is obtained by calculating: Data values Note that above for the number N c does not correspond exactly to the number of bits or coded bits considered earlier, that is to say not only include data, but also control information such as “MAC header”, “RLC header” A method according to claim 1, characterized in that said quality is estimated from the relative net flow, that is to say the ratio between the net rate and gross throughput.
