Abstract

According to various implementations, a device, such as a wireless communication device, carries out the following actions: for each element of a spreading sequence to be applied, determining, based on the element, whether to carry out randomization on a coded data stream, in which each element of the spreading sequence belongs to the set {1, −1, j, −j}; for each element of the spreading sequence for which randomization is determined to be applied, applying, based on the value of the element, one or more randomization techniques to the coded data stream; modulating the coded data stream; and transmitting the modulated data stream.
