Reduction in code blocking using scattered vacant codes for orthogonal variable spreading factor‐based wideband code division multiple access networks

Same rate and pattern recognition search of orthogonal variable spreading factor code tree for wideband code division multiple access networks

“…The cost and complexity of the NOVSF codes is very high. The scattering is reduced by handling non-quantised calls using multi codes in [25].…”

Fixed capacity and variable member grouping assignment of orthogonal variable spreading factor code tree for code division multiple access networks

“…It would be useful to maximise the transmission rate in the homogeneous communication situation as suggested by simulation results. The scattering is reduced by handling non‐quantised calls using multi‐codes in [15]. The quality‐based (QB) assignment and reassignment strategies in [16] handle variable service data rates for an interference limited system which minimises number of code allocation.…”
