This paper presents an improved error-correction decoder for Bluetooth systems employing the expurgated (15,10) binary Hamming code to protect the payload of data medium rate packets. For detection prior to error-correction decoding we consider the application of the limiter-discriminator detector with integrate and dump filter (LDI detector) and a two-state sequence detector (SD), respectively. The proposed decoder exploits the error statistic of the respective detector output and makes use of the single-error-correcting-double-adjacent-error-correcting (SEC-DAEC) capability of the expurgated (15,10) code. As a result, notable improvements in data throughput and/or transmission range are achieved. Since the performance gains come at no additional cost in implementation, the proposed decoder is highly attractive for application in low-cost Bluetooth devices.
