What is Cascade channel?

This paper concerns with the cascaded channel estimation of massive multiple- input multiple-output (MIMO) relay system. It is an advanced MIMO technique consists of a very large number of antennas at the base station and serves a smaller number of single-antenna users simultaneously.

Which type of channel is a binary symmetric channel?

A binary symmetric channel (or BSCp) is a common communications channel model used in coding theory and information theory. In this model, a transmitter wishes to send a bit (a zero or a one), and the receiver will receive a bit.

What is capacity of binary erasure channel?

The binary symmetric channel has a channel capacity of 1 − H(p), where H ( p ) = − p log p − ( 1 − p ) log ( 1 − p ) is the Shannon entropy of a binary distribution with probabilities p and 1 − p. The erasure channel has a channel capacity p, where p is the probability that the transmitted bit is not erased.

What is a binary symmetric channel model?

communications. The binary symmetric channel. This type of channel transmits only two distinct characters, generally interpreted as 0 and 1, hence the designation binary. The probability of correctly receiving either character is the same, namely, p, which accounts for the designation symmetric.

What is channel capacity?

Channel capacity is a much-used metric for the maximum amount of traffic or signal that can move over a particular infrastructure channel. It is useful in computer science, in electrical engineering, and in other disciplines evaluating the capacity of a channel or conduit.

What is a noisy channel?

The noisy channel model is a framework used in spell checkers, question answering, speech recognition, and machine translation. In this model, the goal is to find the intended word given a word where the letters have been scrambled in some manner.

What is binary erasure channel explain?

In coding theory and information theory, a binary erasure channel (BEC) is a communications channel model. A transmitter sends a bit (a zero or a one), and the receiver either receives the bit correctly, or with some probability. receives a message that the bit was not received (“erased”) .

What is binary communication?

telecommunication systems …and distortion-free telecommunication is the binary signal. The simplest possible signal of any kind that can be employed to transmit messages, the binary signal consists of only two possible values. These values are represented by the binary digits, or bits, 1 and 0.

How do I know my channel capacity?

According to channel capacity equation, C = B log(1 + S/N), C-capacity, B-bandwidth of channel, S-signal power, N-noise power, when B -> infinity (read B ‘tends to’ infinity), capacity saturates to 1.44S/N.

How can I increase my channel capacity?

As a result, MIMO technology is able to increase the capacity of a given channel while obeying Shannon-Hartley’s equation. By increasing the number of transmit and receive antennas, a 2 x 2 MIMO system effectively doubles the maximum data rate of what can be achieved in a traditional single RF channel.

What kind of channel is binary erasure channel?

A binary erasure channel (or BEC) is a common communications channel model used in coding theory and information theory.

Which is the binary symmetric channel with erasure probability p?

The binary erasure channel (BEC) with erasure probability p, shown in Fig. 7, models a simple 2-input channel that usually delivers its input correctly, but with probability p outputs an unintelligible symbol (such as noise) which cannot be decoded as either of the inputs and is hence called an erasure. Formally, χ = {0, 1}, Y = {0, 1, e }, and

What is the probability of Erasure in Bec?

The probability of erasure is In coding theory and information theory, a binary erasure channel ( BEC) is a communications channel model. A transmitter sends a bit (a zero or a one), and the receiver either receives the bit correctly, or with some probability
