A variable width barrel shifter. The variable width barrel shifter includes a first barrel shifter configured to receive a data vector of width M as input. The variable width barrel shifter further includes a second barrel shifter configured to receive the data vector of width M as input. The variable width barrel shifter includes an element-wise multiplexer coupled to the first and second barrel shifters. The element-wise multiplexer is configured to provide a shifted output of the data vector of width M by including a first portion of output from the second barrel shifter and a second portion of output from the first barrel shifter.

Synchronizing a pulse position modulation (PPM) signal. A method includes performing a first synchronization operation by receiving a first series of symbols. The symbols in the first series are transmitted with a pulse in a known slot, such that the symbols comprise pulses that are substantially equally spaced in time from adjacent symbols. The first synchronization operation includes identifying when each pulse is received for each of the symbols and using information identifying when each pulse is received for each of the symbols in the first series of symbols to identify symbol and slot boundaries for the pulse position modulation signal. The method further includes performing a second synchronization operation by receiving a second series of symbols transmitted in a known pattern, and identifying the known pattern in the received second series of symbols to identify a frame boundary.
