Abstract:
1. An apparatus, comprising: at least one memory including computer program code; and at least one processor, the at least one memory and the computer program code being configured to, with the at least one processor, cause the apparatus at least to: process a signal including symbols from a transmitter by using Nr receive radiation patterns, the symbols being transmitted so that information content of a symbol of temporal length T is transmitted using the at least two transmit radiation patterns; disable N receive radiation patterns, wherein 1<=N<Nr from the processing of the signal so that Nr−N effective receive radiation patterns are formed; process the signal adapted to Nr−N effective receive radiation patterns so that transmit radiation patterns or the number of symbols in a time interval of length T when receiving with Nr−N effective receive radiation patterns is less than or equal to a separate number of symbols received in a time interval of length T when the apparatus is processing the signal received with Nr receive radiation patterns, wherein the apparatus is configured to process each symbol distributed over at least two transmit radiation patterns by beam-forming wherein the apparatus is configured to process the signal as adapted to a reduced number of receive radiation patterns of the apparatus by changed beam-forming weights.
