Abstract: This paper presents a new multi-carrier DS-CDMA system with multi-code in which input data bits are first coded at a low rate (I/R) and resulting R coded binary bits are then multiplexed ...
Abstract: Orthogonal variable spreading factor (OVSF) codes are employed as channelization codes in wideband CDMA. The quantized rate handling feature of OVSF codes leads to wastage of capacity of ...
