Embodiments of methods and means for passively emulating channels in a multiple-input multiple output (MIMO) system are provided. Such embodiments include passively splitting a plurality of radio frequency signals into a greater plurality of such signals. Each of the greater plurality of radio frequency signals can then be selectively and passively attenuated, delayed and/or phase shifted. The resulting modified radio frequency signals are then recombined crossed over channels and coupled to a plurality of output nodes. Economical and versatile device and system testing is thus facilitated in a low-noise radio frequency environment without the need for complex up/down frequency or analog/digital conversions.

Embodiments of the present invention provide for adaptive cyclic delay diversity to be used in wireless transmissions to mobile devices. The cyclic delay diversity may be adapted through cyclic delay parameters determined based at least in part on a determined speed of the mobile device. Other embodiments may be described and claimed.

Briefly, in accordance with one or more embodiments, in response to receiving a wireless communication signal, a non-uniform codebook is generated based at least in part on one or more characteristics of the received wireless communication signal for quantization and communication back to a source of the received signal. The non-uniform codebook may be generated by selecting a suitable uniform codebook based at least in part on the one or more characteristics of the received wireless communication signal, and supplementing the uniform codebook with additional codewords to generate the non-uniform codebook.

A number format conversion apparatus for signal processing has as inputs an exponent value and a mantissa value, the exponent and mantissa values representing a numerical value for a signal sample. An operator inputs an exponent max/min range and an offset, depending upon what conversion is desired. An output exponent is derived from the input exponent as a function of the maximum and minimum exponent values and the exponent offset. A shift value is derived from an unclipped output exponent and the minimum exponent value. The shift value is applied to a barrel shifter to shift the mantissa value to produce an output mantissa. The output exponent and mantissa form a floating point output number for the signal sample when a floating point output is selected, and the mantissa forms a fixed point output number for the signal sample when a fixed point output is selected. Thus a single circuit, implementable as a block on an ASIC, performs number format conversion between floating point and fixed point number formats.

An improved digital mixer provides means for correcting a conventional mixer output that uses the full range of a mixer control variable to satisfy desired mixer constraints. The correction is accomplished by combining the mix output with a correction signal to satisfy the equation MIX=[A*K+B*/K]+[A*K+B*(/K)]/(2 n)+D.
