In the first phase, each log2 (N t ) bits are mapped into the index of one of the transmitting antennas.
To regenerate the message, the coded bits are mapped into OQAM symbols by performing MT look-up operations.
The proposed HR-DSM transmitter works as follows: At time t+1, (l+m) data bits enter the HR-DSM transmitter, among which l bits are mapped into a n T ×T matrix Xt+1, out of K matrices in the signal space ΩHR−DSM with basic elements drawn from M1−PSK constellation, while remaining m=log2M bits are mapped into a M−PSK constellation symbol xt+1.

The reason is that one error data bit, after convolutional re-encoding, may incur several error coded bits, which in turn are mapped into several incorrect X ^ k, n values in (1).
That is, already detected bits from the initial iteration are fed into the turbo encoder stage and then the coded bits are mapped to obtain the OQAM symbols.
However, such techniques have poor bandwidth utilization as multiple bits are mapped to single narrow pulse.
However, in the coded case, each message bit is encoded by a generator matrix into a number of coded bits which are mapped into any 4/16-QAM constellation point across all symbols.
