Energy Balance Decision Threshold in SDM Systems
Conventional SDM employs an amplitude comparator to convert sampled multi-level signals to a binary level bitstream where negative feedback is used to shape the output distortion spectrum. A modified threshold decision process is proposed that takes a holistic view of the state of the loop. Here a measure related to stored energy within the loop is calculated over a short look-ahead period and then used to select the polarity of the output code at each sampling instant. The motivation is to improve loop stability for high order coders especially for high amplitude input signals as encountered in switching power amplifier applications.
