1. An apparatus for transmitting a broadcast signal, comprising:
a bootstrap generation unit for generating a bootstrap for signaling a system bandwidth field, corresponding to a system bandwidth for a post-bootstrap, and a baseband sampling rate coefficient;
a preamble generation unit for generating a preamble located immediately following the bootstrap in a broadcast signal frame; and
a payload generation unit for generating one or more subframes located immediately following the preamble in the broadcast signal frame,
wherein the baseband sampling rate coefficient corresponds to a sample rate that is set based on a sampling-rate-setting equation defined using a calculation variable (N), which is an integer, in at least one part of a range which is settable with assigned bits,
wherein the baseband sampling rate coefficient is equal to the calculation variable in the at least one part, and
wherein the baseband sampling rate coefficient is different from the calculation variable in another part of the range.
