Abstract
A multifunctional system comprising a turbo decoder, low complexity turbo equalizer and data-aided frame synchronizer is developed to compensate for frequency-selective channels with fading. The turbo codes are based on Partial Unit Memory Codes, which may be constructed with higher free distance than equivalent recursive systematic convolutional codes and can achieve better performance than the latter. The purely digital multifunctional receiver is targeted for end-applications such as combat-radio and radio-relay, providing robust communication at low signal-to-noise ratio with performance approaching the Shannon limit. This paper will present the operation of a multifunctional turbo-based receiver, whose structure is reminiscent of a data-aided turbo synchronizer, both of which are described in detail.
