Abstract
The pure greedy algorithms
matching pursuit (MP) and complementary MP (CompMP)
are extremely computationally simple,
but can perform poorly in solving the linear inverse problems posed by
the recovery of compressively sampled sparse signals.
We show that by applying a cyclic minimization principle,
the performance of both are significantly improved
while remaining computationally simple.
Our simulations show that while MP and CompMP
may not be competitive with state-of-the-art recovery algorithms,
their cyclic variations are.
We discuss ways in which their complexity can be further reduced,
but our simulations show these can hurt recovery performance.
Finally, we derive the exact recovery condition of CompMP and both cyclic algorithms.
