According to some embodiments, an input symbol may be received, and a hard symbol may be generated from the input symbol. A probability associated with the hard symbol may be calculated along with a probability associated with a previous hard symbol. An enhanced symbol may then be determined as a function of a comparison between the probability associated the hard symbol and the previous hard symbol.

System and method for enhanced symbol generation

A noise level of an input signal is determined by a noise calculation module. based on the noise level, a boundary setting module sets a reduced constellation boundary interval. This reduced constellation boundary interval is employed by an equalizer to perform adaptive equalization of the input signal.

Effective adaptive filtering techniques

An architecture and method for flexible preamble processing is disclosed herein. The preamble processing engine detects a code sequence in input, where the code sequence is a sum of a first code sequence and a second code sequence The preamble processing engine includes a data input line, a code input line, a despreader, and a plurality of memory registers. The code input selectively receives the first code sequence or the second code sequence, the first code sequence having a period longer than a period for the second code sequence. The despreader is coupled to the data input line and the code input line. The despreader producing a despread result between the first code sequence and the input data. Lastly, the plurality of memory registers, which are coupled to the despreader, each stores only a portion of the despread results.

Flexible preamble processing for detecting a code sequence

A method for designing an integrated circuit comprises the step of selecting a system-level parameterized module that performs a specified type of function. The method also includes the steps of specifying values for parameters of the selected system-level module and generating a netlist file from the selected system-level module. In one embodiment, the system-level parameterized module is selected from a family of system-level parameterized modules that each perform a particular function within different parameter ranges.
