What is serial to parallel conversion?

The task of a serial to parallel converter is to take a stream of data in serial format and for N-bit parallel converter, give N-bits as parallel output. Parallel data is required in several places like communication in a network, radar equipment etc.

What was the first commercially available system to use OFDM?

In 2001, IEEE issued 802.16, commercially denominated as WiMAX (Worldwide Interoperability for Microwave Access). It became the first OFDM carrier 4G system to be deployed.

Which of the following is used to convert serial to parallel or vice versa?

Solution: Some registers like parallel in serial out and serial in parallel out are used to convert serial data into parallel and vice versa respectively.

How does a 595 work?

74HC595 is a shift register which works on Serial IN Parallel OUT protocol. It receives data serially from the microcontroller and then sends out this data through parallel pins. We can increase our output pins by 8 using the single chip. We can also connect more than 1 shift register in parallel.

What is Rclk?

RCLK (Register Clock / Latch) is a very important pin. When driven HIGH, the contents of Shift Register are copied into the Storage/Latch Register; which ultimately shows up at the output.

What is the function of the SCON?

9. What is the function of the SCON register? Explanation: SCON register is mainly used for programming the start bits, stop bits and data bits of framing. As it consists of bits like RB8, TB8, SM0, SM1, SM2 etc.

What is used to convert data from parallel to serial and from serial to parallel?

One example of such an application specific chip, is the INTEL 8251A [1], which is a Universal Synchronous/Asynchronous Receiver/Transmitter (USART) chip. This chip can be programmed to convert parallel data to serial and vice versa.

What is symbol period in OFDM?

802.11ax introduces a longer OFDM symbol time of 12.8 μs, which is four times longer than the legacy symbol time of 3.2 μs. Subcarrier spacing is equal to the reciprocal of the symbol time. As a result of the longer symbol time, the subcarrier size and spacing decreases from 312.5 KHz to 78.125 KHz.

What is an OFDM symbol?

Orthogonal frequency division multiplexing (OFDM) takes a digital information signal with bit rate Rb, maps n-bit words on to M = 2n symbols (each symbol being a complex number representing the amplitude and phase of an M-ary modulation scheme), splits the resulting symbol stream (rate Rs = Rb/n) into N parallel …
