BPSK modulation with unequal power allocation considering a priori knowledge

Abstract

A well known technique to protect bits with different sensitivities against channel errors is unequal error protection (UEP) by selective channel coding. However, some transmission systems such as Bluetooth and DECT include only weak or no channel coding. For those systems modulation with unequal power allocation (MUPA) is an appropriate technique to… (More)
