    Abstract: The present invention is a system and method for transmitting data symbols in a CDMA communication system including a transmitter having an antenna array and a receiver. The system generates a first and second data field of symbols, then encodes them to produce complex conjugates of the respective symbols. A first communication burst including the first and second data fields, which are separated by a midamble, over a first antenna, and a second communication burst produced using said complex conjugates of said first and second data fields, which are separated by a midamble, over a second antenna are then transmitted by the transmitter. The receiver then receives and decodes the first and second communication bursts to recover the first and second data fields.

    Abstract: An insertion sorter circuit (200) and method are provided which are particularly useful for sorting channel response values of a communication signal. The sorter circuit includes a series of sorter elements (1501-150N) which each have a register (1011-101N). The circuit is configured to cascade values downwardly when one register receives a greater value than it has stored (1021-102N), which value is not greater than the value stored in any upstream register. At the end of processing the values, the most significant values are stored in the registers (1011-101N), the sum (105) of which are the channel power estimate. The channel noise (106) variance is obtainable by applying a system dependent scaling factor to the sum (105) of the least significant values processed.
