Abstract:

High speed downlink packet access (HSPDA) is proposed as the evolution of WCDMA recently, aiming at providing higher downlink transmission rate with peak rate about 8-10 Mbps. Turbo code combined with high order modulation can provide bandwidth efficient transmission with substantial coding gain over traditional trellis coded modulation (TCM). In this paper, author evaluates the feasibility of the application of binary turbo coded modulation (BTCM) with 16QAM in HSPDA. Some improvements of interleaver design according to label mapping are proposed to enhance the performance. And the impact of rate matching functionality on the performance of BTCM is analyzed. Simulation results show that the improved BTCM scheme with 16QAM can be implemented with low code rate and outperform the conventional scheme.
