Process for adjusting the transmission and reception chains of the paths by a base station of a system for radio communication between mobiles

A Process for adjusting a transmission and a reception chain for each path formed by a base station of a system for radio communication with mobiles, said system including a transmission/reception antenna base and a multipath transmission/reception device, comprising after a step of calibrating the antenna base the following steps:

• adjusting the reception chains related to each path by distributing a first specified adjustment signal synchronously over each of the reception chains and calculating an equalization filter which inverts the transfer functions related to each reception chain;
• adjusting the transmission chains related to each path by distributing a second specified adjustment signal synchronously over each of the transmission chains, extracting from each of the paths a part of a transmission signal before the transmission signal is sent to the antenna base so as to re-inject said part into the reception chains, and calculating an equalization filter which inverts the transfer functions relating to each transmission chain;
• receiving reception signals originating from the antenna base via the equalization filters previously calculated for the reception chains, or transmitting the transmission signals originating from the multipath transmission/reception device via the equalization filters previously calculated for the transmission chains.
