  • Carrier constellation information in multi-carrier systems
    Patent number: 7388925
    Abstract: In a multi-carrier system, the carriers (f0 . . . f511, f512 . . . f1023, . . . , f3584 . . . f4095) are grouped in subsets (SUBSET1; SUBSET2; . . . ; SUBSET8). A constellation information transmitting arrangement (BiGi_TA), for instance located in the multi-carrier receiver (RX), produces for each carrier subset (SUBSET1; SUBSET2; . . . ; SUBSET8) a limited set of parameter values (B1, G1; B2, G2; . . . ; B8, G8) and transmits these sets of parameter values (B1, G1; B2, G2; . . . ; B8, G8) to a constellation information receiving arrangement (BiGi_RA), for instance located in the multi-carrier transmitter (TX). Through interpolation of the limited set of parameter values (B1, G1; B2, G2; . . . ; B8, G8) the latter constellation information receiving arrangement (BiGi_RA) determines the constellation where each carrier (f0 . . . f511, f512 . . . f1023, . . . , f3584 . . . f4095) of a carrier subset (SUBSET1; SUBSET2; . . . ; SUBSET8) will be modulated with.
