Effectiveness of Convolutional Codes in WCMDA Systems Supporting High Data Rate Users

چکیده
This article studies the effects of applying convolutional codes to a wideband code-division multiple access (WCDMA) system that supports multirate users. The system is modeled following the WCDMA standards and the channel introduces noise, frequency-selective fading, and MAI. Rate one-half convolutional codes suggested in the third-generation (3G) standards are studied; we find that the error-correcting capabilities provided by these codes are insufficient for supporting very high data rate users. Possible solutions to this problem include employing turbo codes or multiple frequency band transmission.

BLIND PARAMETER ESTIMATION OF A RATE k/n CONVOLUTIONAL CODE IN NOISELESS CASE
This paper concerns to blind identification of a convolutional code with desired rate in a noiseless transmission scenario. To the best of our knowledge, blind estimation of convolutional code based on only the received bitstream doesn’t lead to a unique solution. Hence, without loss of generality, we will assume that the transmitter employs a non-catastrophic encoder. Moreover, we consider a c...

متن کاملSelf-Encoded Multiple Access Multiuser Convolutional Codes in Uplink and Downlink Cellular Systems
Self-encoded spread spectrum eliminates the need for traditional pseudo noise (PN) code generators. In a self-encoded multiple access (SEMA) system, the number of users is not limited by the number of available sequences, unlike code division multiple access (CDMA) systems that employ PN codes such as m-, Gold or Kassami sequences. SEMA provides a convenient way of supporting multi-rate, multi-...
