OFDMA systems inherently take advantages of both frequency diversity gain and frequency-selective scheduling gain. The former is achieved by allocating a user the subcarriers widely scattered over an entire frequency band, while the latter is achieved by allocating a user the subcarriers consecutively located within a subband of a limited bandwidth ...

Diversity gains and clustering in wireless relaying
International Symposium onInformation Theory, 2004. ISIT 2004. Proceedings., 2004We consider a wireless system consisting of one source, one destination and M relays. Assuming path loss and Rayleigh fading, we use the cutset upper bound to show that no matter where the relays are located, the maximum diversity one can obtain is M+1. However, one can achieve a higher diversity gain, namely /spl lfloor/(M+2/2)/sup 2//spl rfloor/, if /

Interference diversity gain in frequency hopping GSM
1995 IEEE 45th Vehicular Technology Conference. Countdown to the Wireless Twenty-First Century, 2002Wideband random frequency hopping is one of the key properties of GSM in an evolution towards PCS (personal communication services). Random frequency hopping introduces diversity on the transmission link, which improves the performance. In this paper, the impact of interference diversity in GSM is analyzed by means of bit level simulations of the GSM ...

Performance gains through diverse top management teams
Team Performance Management: An International Journal, 2004Emerging and future changes in workforce diversity have caused a need to examine the potential impact of these changes on all areas of the firm. One area of special interest is that of top management team (TMT) diversity. With more diverse TMTs on the horizon, there is potential for both conflict and performance gains as a result of increased diversity

An empirical relationship for path diversity gain
IEEE Transactions on Antennas and Propagation, 1976Existing 15.3 and 16 GHz path diversity gain data for earth-space propagation paths are used to generate an empirical relationship for diversity gain as a function of terminal separation distance and single terminal fade depth. The agreement between the resulting closed form expression and the data is within 0.75 dB in all cases.

GSM Multi Antenna Path Diversity Gain Measurement
2008 14th Conference on Microwave Techniques, 2008GSM technology usually uses two antenna paths for uplink on base station. In special cases there are available four antenna paths due to power requirement in downlink on base station for one cell. Because two antenna paths are still necessary for uplink side (reception part), it is appropriate to know, what antenna paths usage is optimum.

DIVERSITY GAIN MEASUREMENTS FOR BODY-CENTRIC COMMUNICATION SYSTEMS
2008In this paper, the implementation of diversity schemes for on-body communication systems at 2.4GHz, 5.8 GHz and 10GHz is investigated. In these systems both the transmitter and the receiver are placed on the body and at a distance that depends on the application in use.
