 	abstract = "In wireless digital communication systems, the transmitted signal may be affected by several sources of distortion, the most significant being Additive Whit Gaussian Noise (AWGN), multipath and Dopplr effect. In environmets where the impulse response of the communication channel is time variant, as in mobile communications, the multipath distortion is dynamic. Together with the Doppler effect, the dynamic multipath may even completely interrupt the wireless communication link. In order to solve this issue, blind channel equalizers are used to mitigate the multipath and Doppler effects. In this context, this dissertation proposes a novel blind channel equalizer, based on the Nonlinear Modified Constant Modulus Algorithm (NMCMA) and on the Soft Direct Desicion (SDD) equalizers in a concurrent architecture. This novel NMCMA-SDD concurrent equalizer is compared with the state of the art, the Constant Modulus Algorithm (CMA)-SDD concurrent equalizer, over the so-called "Brazil channels A-E", proposed by the International Telecommunication Union (ITU). The proposed equalizer presents significant results when compared with the state of the art, making possible its operation in wireless communication links for Unmanned Aerial Vehicles (UAVs), terrestrial vehicles, and others dynamic communication scenarios.",
