Abstract
Methods are described of processing signals received over a wireless communication channel by a receiver in a wireless cellular network. A method includes receiving a sequence of signal samples. The received sequence of samples can be used to estimate at least one channel coefficient for at least one transmission path. An estimate of an orthogonality factor can be generated based on said at least one channel coefficient. An estimate of the disturbance can be generated based on said at least one estimated channel coefficient. An estimate of input signal power can be generated using the received sequence. An estimate of cell geometry can be generated using the estimated orthogonality factor, estimated disturbance, and estimated input signal power. The estimate of cell geometry can be used in processing received data samples. Related methods of processing digital samples are described. Related receivers are also described.
