Abstract:
A multiple modulus conversion (MMC) method, for obtaining a plurality of index values associated with a plurality of moduli, for use in a communication system having means configured to map frames of information bits onto predetermined communication signal parameters, said method comprising:obtaining an input; representing the input as a plurality of sub-quotients; performing a multiplication operation to multiply at least one of the sub-quotients by a multiplicand; determining an index value associated with the multiplicand, the index value being responsive to the inverse modulus multiplication operation; and obtaining a multiplicand that relates to the estimated inverse of a whole number, wherein performing a multiplication operation includes multiplying at least one of the sub-quotients by the multiplicand, wherein the multiplicand is calculated according to the following formula: Ci=floor(B N3/Yi), where B is the base of the numbering system, N3 is the maximum number of digits in the multiplicands, and Yi is the whole number.
