СПОСОБ И УСТРОЙСТВО ДЛЯ ВЗВЕШЕННОГО НЕДВОИЧНОГО КОДИРОВАНИЯ С ПОВТОРЕНИЕМ И НАКОПЛЕНИЕМ И ПРОСТРАНСТВЕННО-ВРЕМЕННОГО КОДИРОВАНИЯ

摘要

An apparatus and method for weighted non-binary RA coding and space-time coding are disclosed. Transmission data is divided in the units of frames each having mN bits, and each frame is further segmented into N blocks, each block containing m bits. The N blocks are converted to N non-binary GF(2) elements. These N non-binary symbols are repeated by a repetition factor r. The rN symbols are multiplied by weighting factors being GF(2) elements other than zero. The rN weighted symbols are interleaved and accumulated. The rN accumulated symbols are transmitted to a receiver, or each of the rN accumulated symbols is demapped to m bits prior to transmission. Therefore, information can be transmitted reliably in a wireless communication system.
