摘要：
In a multi-carrier system, the carriers (f 0 ... f 511 , f 512 ... f 1023 , ..., f 3584 ... f 4095 ) 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 (f 0 ... f 511 , f 512 ... f 1023 , ..., f 3584 ... f 4095 ) of a carrier subset (SUBSET1; SUBSET2; ...; SUBSET8) will be modulated with.
