What is IQ data compression?

What is IQ data compression?

Back to top. Compression IP is used to put more data into a given fiber or microwave “link” in wireless systems. Using Compression a higher data rate can be transmitted on lower speed links which are generally cheaper. This is a goal across the industry but few have achieved.

What is CPRI compression?

To support more carriers or RRUs/RFUs/pRRUs on a CPRI port, the CPRI Compression feature is introduced. This feature compresses the I/Q bit width and lowers the sampling rate to reduce the CPRI bandwidth resources required by the CPRI data transmission.

What are the techniques available for data compression?

Data compression technique is divided into 2 namely lossy compression and lossless compression. But which is often used to perform a compression that is lossless compression. A kind of lossless compressions such as Huffman, Shannon Fano, Tunstall, Lempel Ziv welch and run-length encoding.

What is IQ in CPRI?

A CPRI link consists of at least one radio equipment controller (REC) node and one radio equipment (RE) node. In a cell site, the BBU acts as the REC and the RRH is an RE. These are represented as streams of in-phase and quadrature (IQ) signal samples on the CPRI link.

What are the 2 types of compression?

There are two main types of compression: lossy and lossless.

What is Cpri in LTE?

CPRI Front-Haul Wireless Links for 4G, 5G & LTE Operators. The Common Public Radio Interface (CPRI) standard defines the interface of base stations between the Radio Equipment Controllers (REC) in the standard, to local or remote radio units, known as Radio Equipment (RE).

What is antenna carrier AxC?

AxC is the short form of Antenna Carrier in CPRI standard. Definition: The CPRI standard defines AxCs (antenna carriers) for transmission and reception of the digital I/Q data. An AxC is a container for one I/Q sample. The size in bits of such an AxC thus depends on the length of one IQ sample, e.g. 16 bits.

What are two main types of data compression?

Any kind of data can be compressed. There are two main types of compression: lossy and lossless.

What are some examples of compression?

8 Compression Force Examples in Daily Life

  • Bridge.
  • Hydraulic Press.
  • Spring.
  • Shoe Sole.
  • Bicycle Pump.
  • Sponge.
  • Plush Toys.
  • Air Suspension System.

Which is type of data compression?

Data Compression Methods There are two kinds of compression: Lossless and Lossy. Lossy compression loses data, while lossless compression keeps all the data. Lossless compression allows the potential for a file to return to its original size, without the loss of a single bit of data, when the file is uncompressed.
