摘要:
Timing recovery, with or without frame synchronization, in a cellular TDMA communications system is carried out by a method comprising estimating indirect variables, which embody sampling delay information, of a linear complex vector using a maximum likelihood criterion, and recovering the sampling delay from the estimated indirect variables. For recovering the sampling delay, an optimal procedure and three sub-optimal, but computationally simpler, procedures are described, along with their physical implementations. For frame synchronization, the timing recovery sampling delay is supplemented by a number of sample spacings determined by a maximum of signal amplitudes of a plurality of samples, calculated from the estimated indirect variables and the timing recovery sampling delay.

A splitable modular doghouse includes: a first doghouse body, a second doghouse body, and locking assemblies. A side of the first doghouse body and a side of the second doghouse body can be operatively and detachably connected through the locking assemblies. The doghouse bodies of the splitable modular doghouse are detachably connected through the locking assemblies, so as to adapt to a body size of a dog. Therefore, it is convenient to replace a damaged doghouse body and thus the cost can be reduced consequently.

In various embodiments, a memory cell and a memory are provided. The memory cell comprises a Static Random Access Memory (SRAM) cell including a reset-set (RS) flip-flop and a Read Only Memory (ROM) cell being connected (or coupled) to the SRAM cell to set logic states of internal latch nodes of the RS flip-flop when the ROM cell is triggered. The size of the memory cells proposed in an embodiment of the invention is much smaller than the sum of the size of ROM cells and the size of SRAM cells with the capacity of the memory cells same as the sum of the capacity of the ROM cells and the capacity of the SRAM cells.

An electric motor includes a stator and a rotor installed in the stator. The stator has a laminated stator core and at least two stator windings wound on the stator core. The stator core has at least two stator poles facing the rotor and at least two yokes connecting adjacent stator poles. T stator core is constituted by at least two separate members joined together. The at least two stator poles are only arranged at a single one of the at least two separate members.

A method for informing about power information and a base station are disclosed in the present document. The method includes: a base station informing a user equipment of at least one of the following types of power ratio information through signalings: ratio information of transmission power for transmitting a second category of control signaling information to transmission power for transmitting dedicated demodulation pilots; and ratio information of transmission power for transmitting data information to transmission power for transmitting dedicated demodulation pilots in a subframe where data transmission occupies only one slot. In the example of the present document, when the second category of control signalings and the data are sent, different transmission layers and transmission powers can be selected, which solves the problem resulted from an inconsistency of Demodulation Reference Signal (DMRS) powers and avoids a demodulation error.

A large-span and special-shaped arch bridge, comprising a main girder (2), a center abutment (11) served as a central bearing point and two auxiliary abutments (12,13) served as bearing points at two ends, wherein further comprising an arch-axis combination (3) and two arch-axis bending beams (4,5) presented as arcs projected upwards, the arch-axis combination being built on the center abutment (11) with two ends connected to the inner ends of the two arch-axis bending beams (4,5), the outer ends of the two arch-axis bending beams (4,5) being built on the two auxiliary abutments (12,13), the two arch-axis bending beams (4,5) being connected to the main girder (2) via a plurality of inhaul cables. A method for constructing said arch bridge is also disclosed. Through the dual-arch axis of two arch-axis bending beams, the bending strength of the cross-section of the arch bridge is significantly increased, the bending moment of the cross-section of the arch at the central bearing point is decreased, the vertical displacement at the haunch of the arch is lesser, and the deformation of the main girder is reduced, thus the force of the entire bridge is more reasonable, the construction cost can effectively be reduced and the construction period can be shortened.
