Abstract
Схема с одним кодовым словом (SCW -схема) для приемного устройства малой сложности с минимальной среднеквадратичной ошибкой (MMSE) для рангового прогнозирования, аналогичная схеме с множественным числом кодовых слов (MCW--схема) с последовательным подавлением помех (SIC). Способ рангового прогнозирования содержит этапы, на которых вычисляют матрицы МИМО- канала, соответствующие уровневым передачам для каждого тона, вычисляют отношение "сигнал-шум" (SNR) для каждого тона на основе матриц МИМО- канала, преобразовывают SNR для каждого тона, чтобы сформировать фактические SNR для каждой уровневой передачи, вычисляют величины аддитивного белого гауссовского шума (AWGN), соответствующие фактическим SNR, максимизируют общую спектральную эффективность, основываясь на вычисленных величин
