MIMO Wireless Channel and How to Determine Its Capacity Under Different Conditions

Reach- refers to the number of people who will be exposed to the message via a particular channel

1-2. What are the roles of the source and the receiver in the communication process?

d) We can increase the Maximum possible speed by increasing Signal-to-noise ratio or increasing channel’s bandwidth. However, increasing the channel’s band-width is more efficient in

High-frequency signals are transmitted toward the targets. The transmitted signal is reflected by the target and then received by the same radar.

Putting your messages into codes i.e. sound or light waves is called encoding. Converting the codes back to messages is called decoding.

Network coding allows multiple packets to be transmitted using a smaller number of packets thereby increasing throughput. Here a common single base station transmits data from a common single base station to intermediate stations where it is kept and sent out to the final destination or to any other intermediate stations at a later time. For a traditional network that employs multicast network, the stations receive a packet and forward it to the next node. Under network coding,

Encoded message has to be put in form of signal that is capable of being transmitted. Channel is the means through which the message is to be transmitted to the receiver from the source. Channel can be personal or non-personal. Non-personal channel is may be mass media advertising which can reach a large number of audiences at a time where personal channels such as face-to-face contacts and word of mouth communication can be much more effective and influential and that’s probably because these communications are more flexible and can change with the circumstances.

frequencies which helps avoid some of the single frequency problems. It can usually transmit at only around 250 kps.

* Set of techniques that allows the simultaneous transmission of multiple signals across a single link

It only considers the wavelength of the carrier frequency and the distance between transmitter and receiver, which is usually used for estimate the channel or system design.

Where fh and fL are upper and lower band limits, respectively. Relative bandwidth in excess of 100% are possible for some antenna types.

Shannon Theory, discussed the possible usage of information to define the required transmission Channels’ bandwidth of high frequency transmission channels.

When changing the bits so they can be sent over different types of media this is known as signalling. Signalling will change the bits to what it needs to be for transmission then is read by the connections at the other end.

The characteristics of the channel satellite and mobile communications arm is an important and fast-growing wireless communications and play an important role in the transfer of information through the media of spread from the transmitter to the receiver with the minimum error rate.

Wireless communications is, by any measure, the fastest growing segment of the communications industry. It has captured the attention of the media and the imagination of the public. However, the fundamental phenomenon which makes transmission unreliable is time varying fading. The phenomenon is described as the constructive/destructive interference between signals arriving at the same antenna via different paths, and hence with different delays and phases, resulting in random fluctuations of the signal level at the receiver. This paper investigates Rake receiver method of combating fading.
