Third Generation (3G) of mobile communications systems integrate a wide variety of wireless services as multimedia services. Universal Mobile Telecommunications System (UMTS) is the main standard of 3G with WCDMA air interface. The Code Division Multiple Access (CDMA) provides both error detection and error correction as channel coding scheme. In this paper, block code is considered as the channel coding scheme with soft and hard decision decoder. The observations of block code impact on forward link (downlink) for voice and video services are consider for both soft and hard decision decoder schemes.
