    • Disclosed is a precoding method comprising the steps of: generating a first coded block and a second coded block with use of a predetermined error correction block coding scheme; generating a first precoded signal z1 and a second precoded signal z2 by performing a precoding process, which corresponds to a matrix selected from among the N matrices F[i], on a first baseband signal s1 generated from the first coded block and a second baseband signal s2 generated from the second coded block, respectively; the first precoded signal z1 and the second precoded signal z2 satisfying (z1, z2)T=F[i](s1, s2)T; and changing both of or one of a power of the first precoded signal z1 and a power of the second precoded signal z2, such that an average power of the first precoded signal z1 is less than an average power of the second precoded signal z2.
    • 公开了一种预编码方法,包括以下步骤:利用预定的纠错块编码方案产生第一编码块和第二编码块; 通过对从第一编码块产生的第一基带信号s1和第二编码块产生第一基带信号s1,执行对应于从N个矩阵F [i]中选择的矩阵的预编码处理,生成第一预编码信号z1和第二预编码信号z2 分别从第二编码块产生的信号s2; 第一预编码信号z1和第二预编码信号z2满足(z1,z2)T = F [i](s1,s2)T; 并且改变第一预编码信号z1的功率和第二预编码信号z2的功率中的两者或一者,使得第一预编码信号z1的平均功率小于第二预编码信号z2的平均功率。
