The issues of applying the code-division multiple access (CDMA) technique to an on-chip packet switched communication network are discussed in this paper. A network-on-chip (NoC) that applies CDMA is realized register-transfer level (RTL) using VHDL. NoC supports globally-asynchronous locally-synchronous (GALS) scheme by both synchronous and asynchronous designs. In a NoC, which point-to-point connection scheme, e.g., ring topology data transfer latency varies largely if packets transferred...

Indoor positioning based on IEEE 802.11 wireless LAN (Wi-Fi) fingerprinting needs a reference data set, also known as radio map, in order to match the incoming fingerprint operational phase with most similar set and then estimate device position indoors. Scalability problems may arise when map is large, e.g., providing large geographical areas or involving crowdsourced collection. Some researchers divide into smaller independent clusters, such that search area reduced less dense groups than...
