The English quadraturephaseshiftkeying abbreviation, stands for orthogonal phase shift keying, is a digital modulation method. The four-phase Phase Shift Keying Signal is short for "PSK ". It can be divided into absolute phase shifting and relative phase shifting. The following figure shows the principle of the following: The following digital demodulation methods are available: analog-to-digital conversion, extraction or interpolation, matching filtering, clock and

example, the serial Receive Buffer contains characters, or the carrier detect (CD) or request to send (RTS) when a character arrives online or a change occurs. In these cases, you can use the oncomm event of the MSComm control to capture and process these communication events. The oncomm event can also check and handle communication errors. For a list of all communication events and communication errors, see commevent attributes. In the programming p

not the real distance between the user and the satellite, but a pseudo distance (PR): When the GPS satellite works normally, the system constantly uses a pseudo-random code (pseudo code) consisting of 1 and 0 binary code elements to send navigation messages. There are two types of pseudo-code used by the GPS system: Civil c/a code and military P (y) code. The C/A code frequency is 1.023 MHz, and the repetition period is one millisecond. The Code interval is 1 microsecond, equivalent to 300 m. T

What are the LTE downlink reference signals and upstream reference signals?In R9, the downlink defines four reference signals, respectively, for the cell-specific reference signal (C-RS), the user-specific reference signal (UE-RS, also known as Dm-rs), MBSFN reference signal, position reference signal (P-RS).In R10, the downlink defines five reference signals, namely, the cell-specific reference signal (C-RS), the user-specific reference signal (UE-RS, also known as Dm-rs), the MBSFN reference s

height and the antenna pitch angle and the direction angle are in the normal range, but the antenna standing wave ratio is as high as 1.7. During further checks on the base station's installation status, it is found that the loose antenna interface causes the standing wave ratio to increase, the direct cause of reduced coverage.
