  • Method of allocating a transmission power level to pilot symbols used for estimating the channel of a transmission system of the multicarrier type with spreading of the signal in the frequency domain by spreading sequences
    Patent number: 7061881
    Abstract: A method of determining transmission power of transmitted pilot symbols used for estimating channel coefficients in a transmission frame of a multicarrier transmission system having OFDM-CDMA, MC-CDMA, MC-CDM or MC-SS-MA frequency domain spreading sequences. The method includes determining a performance level to be achieved by the transmission, deducing the signal to noise ratio level introduced by the channel from the performance level to be achieved, deducing a single code transmission power Q0 of the pilot symbols for a single spreading code from the signal to noise ratio level, deducing an increase in power ? for transmitting the pilot symbols using a number of spreading codes K, and determining the transmission power Q of the pilot symbols at predetermined times, based on the following equations: Q=?(K?1)+Q0; K>1; ?>0; and Q0>?.
