Abstract

DC60 Provided is a pre-coding method for generating multiple pre-coded signals to be transmitted simultaneously over the same frequency band from multiple baseband signals, comprising the steps of selecting a matrix (F[i] from among N matrices defining the pre-coding range performed over the multiple baseband signals while switching between the N matrices, where i is an integer from 0 to N-1 and N is an integer with the lowest value being two), generating a first pre-coded signal z1 and a second pre-coded signal Z2, generating a first encrypted block and a second encrypted block using a specified error-correcting block coding method, generating a baseband signal of M symbols from the first encrypted block and a baseband signal of M symbols from the second encrypted block, and encoding and combining the pre-generated baseband signals to generate a pre-coded signal with M input channels. Provided is a pre-coding method for generating multiple pre-coded signals to be transmitted simultaneously over the same frequency band from multiple baseband signals, comprising the steps Selecting a matrix (F[i] among N matrices that define the precoding region performed on multiple baseband signals, while shuffling between N matrices, where i is an integer from o to N-1 and N is an integer with the lowest value two, generating a first pre-encoded signal z1 and a second pre-encoded signal Z2, generating a first encrypted block and a second encrypted block using a given error-correcting block coding method, generating a baseband signal of M symbols from the first encrypted block and a baseband signal of M symbols from the second encrypted block, and encoding and combining the pre-generated baseband signals to generate a pre-encoded signal with M input channels.
