A memory system including a read module, a demultiplexer, an acquisition module, a tracking module and a control module. The read module is configured to (i) read pilot data and user data stored in a block of a first memory and (ii) generate read signals based on the pilot data and the user data. The demultiplexer is configured to, based on the read signals, generate pilot signals and user data signals. The acquisition module is configured to (i) receive the pilot signals and (ii) generate a first estimate of a signal-to-noise ratio of the block of the first memory based on a predetermined pilot pattern. The tracking module is configured to generate a second estimate of the signal-to-noise ratio of the block of the first memory based on the user data signals. The control module is configured to generate recovered data based on the first estimate and the second estimate.
