Is the spreading factor for the ith ray. is the incident ﬁeld immediately adjacent to the corresponding transmission or reﬂection point. The spreading factor depends on the distances to the source and ﬁeld points and on the curvature of the reﬂection or transmission boundary. For spherical waves and plane boundaries, Ai / 1=ri , whereas for plane waves and plane boundaries, Ai does not vary with distance. Parameters with a subscript 0 account for the direct ray from source to ﬁeld point, if unobstructed.
Chapters 17 and 18 will introduce two further multiple access schemes, orthogonal frequency division multiple access (OFDMA) and space division multiple access (SDMA). The duplexing schemes described here are frequency division duplex (FDD) time division duplex (TDD). 15 illustrates a system using FDMA and FDD. The total bandwidth available to the system operator is divided into two sub-bands and each of these is further divided into a number of frequency channels. Each mobile user is allocated a pair of channels, separated by the duplex spacing, one in the uplink sub-band, for transmitting to the base station, the other in the downlink sub-band, for reception from the base station.
