Comments on 'The coverage-capacity tradeoff in cellular CDMA systems'
In cellular CDMA systems that employ single-user detectors, in-cell interference limits the coverage of the cell. Thus for a given upper limit on transmit power, the coverage of a cell is inversely proportional to the number of users in it. This tradeoff between coverage and number of users is explicitly characterized here. Our analysis may be used in cellular planning to set hard limits on the...

متن کاملCapacity Evaluation for CDMA Cellular Systems
In this paper, we find bounds and approximations for the capacity of mobile cellular communication networks based on Code Division Multiple Access (CDMA). We develop efficient analytic techniques for capacity calculations of CDMA cellular networks. Each cell is modeled as an independent M=G=1 queue and traffic capacity assessed based on the maximum Erlang traffic that leads to acceptable link q...
متن کاملThe coding-spreading tradeoff in CDMA systems
General definitions of spreading and coding are given based on the notion of Shannon bandwidth introduced by Massey (1994), with the goal of distinguishing these operations for signaling with bandwidth redundancy. These definitions are shown to lead to a separation result: every bandwidth redundancy scheme can be expressed as a concatenation of coding followed by spreading. The coding-spreading...
