System object: comm.MultiplexedDeinterleaver
Deinterleave input symbols using a set of shift registers with specified delays
Y = step(H,X)
Y = step(H,X) restores the original ordering of the sequence, X, that was interleaved using a multiplexed interleaver and returns Y. The input X must be a column vector. The data type for X can be numeric, logical, or fixed-point (fi objects). Y has the same data type as X. The multiplexed deinterleaver object uses N shift registers, where N is the number of elements in the vector specified by the Delay property. When a new input symbol enters the deinterleaver, a commutator switches to a new register. The new symbol shifts in while the oldest symbol in that register is shifted out. When the commutator reaches the Nth register, upon the next new input, it returns to the first register. The multiplexed deinterleaver associated with a multiplexed interleaver has the same number of registers as the interleaver. The delay in a particular deinterleaver register depends on the largest interleaver delay minus the interleaver delay for the given register.
Note: The object performs an initialization the first time the step method is executed. This initialization locks nontunable properties and input specifications, such as dimensions, complexity, and data type of the input data. If you change a nontunable property or an input specification, the System object™ issues an error. To change nontunable properties or inputs, you must first call the release method to unlock the object.
