1. A method for constructing a data frame, the method comprising the steps of:

  • dividing, by a processor, a frame into a plurality of partitions;

    for each of the plurality of partitions, determining, by a processor, a length of an associated OFDM symbol;

    calculating, by a processor, a sum of OFDM symbol lengths in a union of the OFDM symbols over the plurality of partitions;

    computing, by a processor, a number of excess samples based on the calculated sum and based on a length of a payload region of the frame; and

    for each OFDM symbol in the union, assigning, by a processor, the OFDM symbol to one of at least one subset of the union using at least one of the number of excess samples and an index of the OFDM symbol, and adding a number to a cyclic prefix size of each OFDM symbol in each of the at least one subset of the union, prior to embedding the OFDM symbols in the frame.
