Abstract: A method of receiving data transmitted by a plurality of communications devices includes receiving at each of a plurality of M antennas reference signals transmitted by each of a plurality of K communications devices, and processing by each of a plurality of antenna modules the reference signals. The processing by each of the antenna module includes estimating for each of the K detected reference signals received from the K communications devices a sample of a radio channel through which the received signals have passed, generating for each of the K samples of the radio channel a K×K partial matrix forming a part of a signal processing matrix for performing zero forcing equalisation of the received signals, and transmitting the partial matrix K×K from each of the M antenna modules to a central processing unit.

Abstract: A method of receiving data transmitted by a plurality of communications devices comprises receiving at each of a plurality of M antennas reference signals transmitted by each of a plurality of K communications devices, and processing by each of a plurality of antenna modules the reference signals, each of the antenna modules being connected to a corresponding one of the plurality of antennas. The processing by each of the antenna module includes estimating for each of the K detected reference signals received from the K communications devices a sample of a radio channel through which the received signals have passed, generating for each of the K samples of the radio channel a K×K partial matrix forming a part of a signal processing matrix for performing zero forcing equalisation of the received signals, and transmitting via a communications interface the partial matrix K×K from each of the M antenna modules to a central processing unit.

Abstract: Shower apparatus (1) heated by solar apparatus radiation (3) used in open spaces, made of any type of material, and installed in a substantially vertical position, which comprises the structural configuration of the apparatus in addition to act as accumulation container (2) of water heated by sunbeam (3), so that the vertical cylinder (2) made of rigid material is used both as an accumulator storage of hot water and as a carrier structure for the apparatus. The storage cylinder may be coated with a protection cover which avoids the cooling produced by ambient air.
