WebJun 6, 2005 · The QSBM demodulator 24 is computationally as efficient as the conventional quaternary CPM demodulator, yet requires significantly fewer storage elements as it needs not store the survivor path states when generating the soft bit metrics using the QSBM generator 32. The QSBM demodulator 24 can be applied to a convolutional-coded … Continuous phase modulation (CPM) is a method for modulation of data commonly used in wireless modems. In contrast to other coherent digital phase modulation techniques where the carrier phase abruptly resets to zero at the start of every symbol (e.g. M-PSK), with CPM the carrier phase is modulated in a continuous manner. For instance, with QPSK the carrier instantaneously jump…
