  A channel with continuous phase modulation and 1-bit ADC with oversampling is
considered. Due to oversampling, higher-order modulations yield a higher
achievable rate and this work presents a method to approach this with
sophisticated coding. A tailored bit mapping is proposed where two bits can be
detected reliably at high SNR and only the third bit suffers from an error
floor. With this, a convolutional code is only applied to the third bit. Our
experiments with a turbo receiver show that the proposed method corresponds to
a lower BER in comparison to the case of conventional channel coding.
