摘要：
Blind detection is one of the most perspective techniques in signal processing theory. In this, paper we describe blind detector based on the linearly constrained constant modulus algorithm (LCCMA). Simulations are oriented on multi-carrier code division multiple access (MC-CDMA) signals when turbo codes are used for error corection of transmitted images. We had investigated the system hit error rate (BER) performance in 3-states channel enlarged with a complex AWGN (aditive white Gauss noise) noise. The channel model is assigned for Land mobile satellite (LMS) communications. The application of turbo coding strengthens the system ability to cope with multi-path fading and multi-access interference (MAI) significantly.
