    Abstract: 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.

    Abstract: 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.

    Abstract: 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.

    Abstract: 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.
