Many TCM codes do not shape the power spectrum. It is desirable to shape the power spectrum of the coded modulation to compensate for the linear filtering effect of the channel, in order to maximise the data transmission rate. A technique is proposed whereby several independent TCM codes are used to encode different subbands of the available transmission bandwidth such that they can all be decoded efficiently in a single decode
