The amazing performance of the concatenated codes led to attract many researchers to study these characteristics and use theme in many applications in recent years. Because the concatenated code theory is not built from the previous theories, so the characteristics of these codes remain under study and clarification. Recently, the concatenated codes became one of the main options for forward error correcting codes (FEC) in third generation mobile standards such as Universal Mobile Telecommunications System UMTS. This paper investigates the effect joint source –and channel coding which is considered a proficient system for wireless transmission. A new class of FEC is used which is known as a precoder of rate 1 as inner code and non recursive turbo code as outer encoder for hybrid system and then compared with the performance of UMTS turbo code standard for DCT compressed image.
