1. An apparatus for communication in a wireless communication network, the apparatus comprising:
a coder configured for encoding a set of data symbols to produce a set of coded symbols;
a modulator configured for modulating the coded symbols onto a set of subcarrier frequencies to generate a time-domain signal comprising a sum of a set of modulated pulse waveforms; and
a transmitter configured for transmitting the time-domain signal in the wireless communication network;
wherein the coder employs a matrix of spreading codes, each column of the matrix multiplying a different one of the set of data symbols to cause the modulating to produce a corresponding one of the set of modulated pulse waveforms; and
wherein each column of the matrix of spreading codes comprises a set of linearly increasing phases configured to provide a time offset to the corresponding one of the set of modulated pulse waveforms.
