1. Background information Wireless and mobile communications is one of the fastest growing areas of modern life. It has an enormous impact on almost every aspect of our daily lives. A world of ubiquitous wireless devices is emerging, from wireless sensors and tags to mobile terminals. There are a number of wireless systems and networks in operation such as GSM, GPRS, EDGE, UMTS, IEEE 802.11, and Bluetooth, and several multiple access techniques including MC-CDMA, W-CDMA, and OFDM are used. Long-range cellular communication encompasses the evolution from GSM to 3G systems. It aims to achieve full mobility and global roaming for individual links maximizing system capacity. In short-range wireless networking and wireless connectivity, WLAN or PAN covers local hot spot areas for very high data rate asymmetric individual links (e.g. IEEE 802.11, HIPERLAN). Also fixed wireless local loops provide wireless access from street to home for broadband internet and multimedia services.[1]

    Wireless Signals

    Wireless signals are all around us as we walk or drive around the city or town where we live. The four types of wireless technologies that are out there are Wi-Fi, Cellular, Bluetooth, and WiMAX. We will be looking at these types of wireless technologies a little more in depth, where are they most commonly used, and how they differ from one another. The first wireless technology that we will be looking at is the Wi-Fi wireless signal. The Wi-Fi signal is mainly associated with computer networking, the specification used to create a wireless local area network is the IEEE 802.11. One would use this type of wireless technology if you were a business owner opening up a coffee shop and needed a public network. The network would have a wired connection to an internet source, then leading to a wireless router that transmits and receives the data from all of the customer’s devices that want to use the Wi-Fi. This will also connect all of the devices to one another through the network. The next type of wireless technology that we will be looking at is Cellular. This type of wireless technology is most often associated with wireless telephones. The cellular network is connected to cells that will enable a user to move around freely while staying connected to the network. This type of signal is used everywhere you go nowadays and are used by everyone. There are a multitude of devices that use these networks at one time and those include, smart phones, tablets, and some computers can use the cell towers to get a signal to be able to use the internet. The first generation of cellular signals was completely analog, and from there with the growing demand of faster speeds and better connectivity technology brought us 2G, 3G, and the ever popular 4G phones. Bluetooth is the next technology that we will touch on and is very similar to the Wi-Fi and cellular networks but on…

    Ofdm

    I. I NTRODUCTION The American IEEE802.11a standard and the European equivalent HIPERLAN/2 are two similar concepts for broadband wireless LANs (WLAN) in the 5 GHz band. Both standards are based on the multicarrier modulation technique OFDM (orthogonal frequency division multiplexing) combined with convolutional channel coding. The baseband modulation schemes of both standards are very similar, which simplifies implementation considerably. Challanges and difficulties considered in this paper regard both systems. Except for slight differences in signal mapping, most discrepancies between the standards regard the higher protocol layers. Section II presents some fundamentals of OFDM and the WLAN standards. Here we focus on the baseband modulation in the PHY layer and explain parts of the PHY burst structure relevant to channel estimation. Section III describes a frequency domain channel estimator. Assuming channel impulse responses being…
