Abstract
A wireless network includes a set of nodes. Each node includes a transmitter and a receiver. A block of data bits is converted to a block of data symbols. The block of data symbols is partitioning timewise into groups of data symbols. A set of subcarriers is assigned to each group of data symbols, and each group of data symbols is spread to a chip sequence using a coding block of spreading sequences, wherein the spreading sequences are based on types of the groups of data symbols. Then, after the spreading, the chips are transmitted as orthogonal frequency-division multiplexing (OFDM) data symbols on the assigned subcarriers.
