Abstract :
Recently, a new noncoherent sequence detection receiver for Bluetooth systems has been developed. The receiver is based on Rimoldi´s decomposition of the Bluetooth transmit signal and its power efficiency was shown by software simulations. In this paper, a hardware implementation of the decoder for this receiver is presented. In particular, we describe a low-complexity Viterbi decoder that performs noncoherent sequence detection in a two-state trellis using per-survivor processing. The prototype decoder is implemented in a field programmable gate array (FPGA). The bit-error-rate performance of the implemented decoder is compared with that of the reference software simulations
