This paper investigates the design and performance of delayed bit-interleaved coded modulation (DBICM) with low-density parity-check (LDPC) codes. For Gray labeled square M-ary quadrature amplitude ...

Brushless dc motors (BLDCMs) exhibit relatively large torque ripple due to the current pulsation during the commutation process. In this paper, first, the production mechanism of the commutation ...

A Bluetooth pulse code modulation (PCM) lookback test primarily verifies the functionality of the Bluetooth chip’s PCM ...
