Communications system employing orthogonal frequency division multiplexing based spread sprectrum multiple access

Apparatus for use in an orthogonal frequency division multiplexing (OFDM) based spread spectrum multiple access wireless system comprising:

• a sequence generator for generating one or more sequences;
• a sequence assignor for assigning one or more of said one or more sequences on a time slot to time slot basis;
• and
• a a tone assignor responsive to said generated one or more sequences and to said assignment of said one or more of said sequences for assigning one or more tone sequences to a user on said time slot to time slot basis.

• a transmitter including
• a first sequence generator for generating one or more sequences,
• a first sequence assignor for assigning prescribed one or more of said one or more sequences generated by said first sequence generator on a time slot to time slot basis, wherein assignment is effected of a prescribed one or more of said sequences in a time slot, and
• a tone assignor responsive to said one or more sequences generated by said first sequence and to said assignment of said prescribed one or more of said sequences assigned by said first sequence assignor for assigning one or more tone sequences to a user on said time slot to time slot basis;
• and
• a receiver including
• a second sequence generator for generating one or more sequences,
• a second sequence assignor for assigning prescribed one or more of said one or more sequences generated by said second sequence generator on a time slot to time slot basis, wherein assignment is effected of a prescribed one or more of said sequences in a time slot, and
• a tone identifier responsive to said one or more of sequences generated by said second sequence generator and to said assignment of said prescribed one or more of said sequences assigned by said second sequence assignor for identifying incoming tone sequences to a user on said time slot to time slot basis.
