Abstract: A method for channel estimation, performed by a wireless transmit/receive unit (WTRU), includes: receiving a plurality of input signals, generating a plurality of sensing matrices for the input signals, generating an augmented sensing matrix and an augmented observation vector according to the sensing matrices and the input signals, estimating a plurality of channel delay parameters according to the augmented sensing matrix and the augmented observation vector, and estimating channel information according to the channel delay parameters.

Abstract: An electronic device with a missed-call management includes a signal triggering module, a driving circuit, and an indicating circuit connected in that order. When there is a missed call, an incoming call signal of the electronic device is received by the signal triggering module. According to the received incoming call signal, the signal triggering module controls the indicating circuit to work.

Abstract: A transceiver connector (100) includes a housing (1) having a number of faces including a primary face (10) and a pair of side faces (13) and a collar clip (2). The collar clip includes a base at least partially surrounding the plurality of faces of the housing. The primary face defines at least one vertically extending locking recess (104) having a stepped portion (1041). The collar clip includes a base (20) at least partially surrounding the number of faces of the housing. The base includes at least one locking beam (204) inserted into the corresponding locking recess of the housing along a first direction and having a click portion (2041) engaging with the stepped portion of the housing along a second direction perpendicular to the first direction.

Abstract: A power supply device includes a power supply module, a main bus-bar module, an assistant bus-bar module, and a plurality of connectors. The power supply module, for supplying a direct current voltage, includes a positive terminal and a negative terminal for outputting the current voltage. The main bus-bar module includes a first main bus-bar and a second main bus-bar. The first main bus-bar is electronically connected to the positive terminal. The second main bus-bar is electronically connected to the negative terminal. The assistant bus-bar module includes a first assistant bus-bar electronically connected to the second main bus-bar, and a second assistant bus-bar electronically connected to the first main bus-bar. Each connector includes a first pin and a second pin. The first pin is inserted and electronically connected to the first assistant bus-bar. The second pin is inserted and electronically connected to the second assistant bus-bar.
