This paper considers the application of the proposed asymmetric turbo code system [4,5] in MIMO High Speed Downlink Packet Access (HSDPA) service of WCDMA. In typical turbo code system [3], an encoder with code rate 1/3 is used together with bit repetition to achieve the code rate 1/4. However, this approach suffers from weak Bit Error Rate (BER)(More)
In this paper, a modified optimal power allocation scheme for different bits in turbo encoder has been proposed to improve the performance of Turbo Codes system in High Speed Downlink Packet Access (HSDPA) service. In a typical turbo code in HSDPA system, an encoder with code rate of 1/3 was used with bit repetition scheme or puncturing system to achieve(More)
