Apparatus and Method of Space Time Block Code Lattice Encoding using Interface Memory

摘要

A space time block code lattice encoding apparatus using an interface memory and a method thereof are provided to reduce resource usage by performing a space time block code lattice encoding without an additional memory. A space time block code lattice encoding method using an interface memory include the steps of: reading an SDCH(Scheduled Data Channel) data of first and second OFDM(Orthogonal Frequency-Division Multiplexing) symbol sections from an interface memory for a first OFDM symbol section(302); encoding the SDCH of the first and second OFDM symbol sections through a space time block code scheme(304); allocating a resource based on the encoded result and resource allocation control information stored in the interface memory(306); modulating a signal to which the resource is allocated(308) in the first OFDM symbol section; in the second OFDM symbol section, transmitting a modulation signal corresponding to the SDCH data of the first OFDM symbol section(310); and in a third OFDM symbol section, transmitting a modulation signal corresponding to the SDCH data of the section OFDM symbol section(312).
