A novel indoor localization method for Wi-Fi devices such as smart phones is presented. With an indoor path loss model, the distance between a mobile device (MD) and an access point (AP) can be estimated form the received signal strength (RSS). Then, least-squared-error (LSE) triangulation yields the position of the MD. Though indoor channel characteristics(More)
We present a recursive single parity check product code, which was originally introduced as a constant amplitude multi-code CDMA. The proposed code has two advantageous features over conventional parity check product codes. First, the proposed code does not have any low-weight codewords. We derived a closed-form solution for the weight distribution. The(More)
