The fractionally spaced vector constant modulus algorithm


The vector constant modulus algorithm (VCMA) was recently introduced as an extension of CMA which can equalize data from shaped sources having nearly Gaussian marginal distributions. Some simple changes in the structure of VCMA allow it to be used in fractionally-spaced equalizers with their attendant benefits. Although developed with shell mapping in mind, VCMA can also equalize data from other shaping methods such as trellis shaping. Furthermore, the vector modulus concept from VCMA can be successfully applied to other algorithms based on constant modulus criteria, including RCA and MMA. Simulations have verified all of these results.
