Performance evaluation of proposed asymmetric turbo code in WCDMA HSDPA system

This paper considers the application of the proposed asymmetric turbo code system in MIMO High Speed Downlink Packet Access (HSDPA) service of WCDMA. In typical turbo code system, an encoder with code rate 1/3 is used together with bit repetition to achieve the code rate 1/4. However, this approach...

In typical turbo code system, an encoder with code rate 1/3 is used together with bit repetition to achieve the code rate 1/4.

In this paper, we used the proposed asymmetric turbo code system to mitigate the weak BER performance introduced in bit repetition scheme.

The performance of typical turbo code and proposed asymmetric turbo code using bit repetition and puncturing schemes is studied in MIMO HSDPA system using MATLAB simulation and compared. From the simulation results, it is observed that the proposed asymmetric turbo code system performs better and it provides coding gain of 0.2dB to 0.3dB and the total throughput is also increased up to 10% compared to typical turbo code system in MIMO HSDPA.
