Sistem seluler Wideband Code Division Multiple Acces (WCDMA) saat ini berkembang sangat pesat pada tugas akhir ini dilakukan Analisa Unjuk Kerja Sistim Downlink Dedicated Channel (DCH) pada Wideband CDMA. Untuk menganalisa performa atau unjuk kerja dari sistem Downlink DCH pada Wideband CDMA dicari nilai kesalahan bit pada saat pengiriman yang biasa dikenal dengan nama Bit Error Rate pada Cyclic Redundancy Check (CRC) dan channel coding dengan input Dedicated Traffik Channel (DTCH) dan Dedicated Control Channel (DCCH) dicari nilai Bit Error Rate (BER) pada sistem Downlink Dedicated Channel (DCH) Wideband CDMA dan dicari nilai Block Error Rate (BLER) pada sistem Downlink Dedicated Channel (DCH) Wideband CDMA. Analisa ini menggunakan piranti lunak Matlab 7.0.1 untuk mengetahui jumlah kesalahan Bit Error Rate (BER) dengan jenis kanal Multipath Fading. Dari hasil simulasi dengan Input 106 pada 7 dB dengan menggunakan Eb/No dari 1 hingga 7 dB maka didap atkan Bit Error Rate dengan nilai Bit Error Rate BER 1,8 x 10^-6.

The Physical Control Format Indicator Channel (PCFICH) is one among the downlink physical control channel and it carries the number of OFDM symbols used by the PDCCH channel, denoted as Control Format Indicator (CFI).These control channels play a key role in the correct decoding of the payload information. The CFI is the first information received by the User and so is important for the system performance. In this paper, Research on the PCFICH in eNodeB, a simple implementation approach is proposed in the TMS320C64xDSP, The program has been applied to the development of LTE-TDD wireless integrated test instrument. The running results verify that the program is feasible and effective.

Abstract. This article gives a comparison of beamforming concepts. Adaptive beamforming and fixed beam switching in WCDMA-FDD-mode are compared from a system level perspective, ordinary sectorization (three 120° sectors) serves as a basis for comparison. Pilot channels P-CPICH (Primary Common Pilot Channel) and S-CPICH (Secondary CPICH) are considered as additional interference. For adaptive beamforming channel estimation has to be based on the pilot bit sequence on DPCCH (Dedicated Physical Control Channel) which leads to degradation especially for high mobile velocities and large angular dispersions of the multipath channel.
