Abstract: Frequency hopping in an IFDMA system takes place by utilizing a time-varying IFDMA modulation code. In particular, a modulator (102) receives a symbol stream and a user specific IFDMA modulation code (b^[igrave](t)) (112). The output of the modulator comprises a signal (X^i(t)) existing at certain frequencies, or subcarriers (114). The actual subcarriers that signal X^i(t) utilizes is dependent upon the repetition of the symbol blocks and the particular IFDMA modulation code utilized (108).

Abstract: A method and apparatus for using both D-FDMA and L-FDMA within a same frequency band is provided herein. The proposed technique scatters the sub-carriers of each D-FDMA user to a frequency band utilized by L-FDMA communications without separating the total band into exclusive D-FDMA and L-FDMA sub-bands. The L-FDMA users are assigned to the gap of the D-FDMA sub-carriers. Therefore, frequency diversity gain of D-FDMA by the proposed method is larger than if D-FDMA and L-FDMA sub-bands were created.

Abstract: A method and system for adaptive control of sub-carriers is useful for increasing frequency diversity gain to improve bit error rate performance in an Interleaved Frequency Division Multiple Access (IFDMA) system. The method includes selecting a combination of a Repetition Factor (RF) and a repetition block size (Q), from possible combinations of a RF and a Q, based on a number of users (Nu) (step 1405). A Spreading Factor (SF), Forward Error Correction (FEC) coding rate (R), or modulation order (M) based on the Nu is then determined (step 1410). Control signals are then provided based on the RF and Q, and based on the SF, R, or M (step 1415).

Abstract: A method and apparatus is provided for transmitting an orthogonal frequency domain multiple access (OFDMA) signal including a synchronization channel signal transmitted including a plurality of sequence elements intereleaved in time and frequency (610, 640). The synchronization channel signal sequence elements enable an initial acquisition and cell search method with low computational load by providing predetermined time domain symmetry (702, 704) for common sequence elements in OFDMA symbol periods (620, 660) for OFDMA symbol timing detection and frequency error detection in an OFDMA system supporting multiple system bandwidths, both synchronized and un-synchronized systems, a large cell index and an OFDMA symbol structure with both short and long cyclic prefix length.
