# Is CMA equalization applicable for OFDM

I have a question regarding the constant modulus algorithm (CMA), as you know it's one of the known algorithms used for blind equalization. The cost function of the CMA is build blindly, it means based on received signal only. The cost function of that algorithm is:

$$J = \frac12\left[\left\lvert w^T*y(n)\right\rvert^2 - R_{cm}\right]^2$$

where $$R_{cm}$$ is the constant of CMS algorithm which is usually equals 1. $$w^T$$ is the equalizer coefficients and $$y(n)$$ is the received signal.

My question, is that algorithm applicable for OFDM system?

If so, and what's the constant $$R_{cm}$$ will be?
